PetroCorp Amended 2000 Annual Report on Form 10-K/A ii QUESTIONS AND ANSWERS ABOUT THE MERGER Q: Why are PetroCorp and Southern Mineral proposing the merger? A: Our companies are proposing the merger because we believe that the combined company will be able to compete more effectively for, and secure, growth opportunities, including accessing capital resources adequate to pursue a more expansive exploration and development plan. The combined company expects to benefit from combining the companies' operations in their core operating area, the Gulf Coast region, while also benefiting from greater diversity of operations in the Gulf Coast region and the added diversity of properties in Canada. We also believe that the merger will result in improved shareholder liquidity, including the opportunity it gives Southern Mineral shareholders to receive cash payments for their Southern Mineral shares at a fair price or to continue as a shareholder of the larger and more diverse combined company. Please read the more detailed description of our reasons for the merger on pages 28 through 32. Q: What will happen to Southern Mineral shares in the merger? A: In exchange for each share of Southern Mineral stock, Southern Mineral shareholders will receive merger consideration of $4.71 in cash or, if the shareholder timely elects, in PetroCorp common stock based on an exchange ratio of .471, subject to possible proration as a result of oversubscription for PetroCorp stock, as described below. Q: What happens if PetroCorp's and Southern Mineral's shareholders approve the merger and Southern Mineral's shareholders elect to receive more than 4,000,000 or less than 3,000,000 shares of PetroCorp stock? A: Regardless of the number of shares of PetroCorp common stock desired by Southern Mineral shareholders, Southern Mineral shareholders will not receive as a result of stock elections more than 4,000,000 shares in the merger. If the Southern Mineral shareholders elect to receive more than 4,000,000 shares of PetroCorp stock, the 4,000,000 shares available for issuance will be prorated among shareholders electing to receive stock. For example, if Southern Mineral shareholders make elections to receive 5,000,000 shares of PetroCorp stock in the merger, each shareholder electing stock will receive only 80% (4,000,000 / 5,000,000) of the number of PetroCorp shares requested. Any merger consideration that is not paid in PetroCorp stock will be paid in cash. If Southern Mineral shareholders do not elect to receive at least 3,000,000 shares of PetroCorp common stock, PetroCorp will not be obligated to complete the merger. However, PetroCorp may waive this condition to the merger closing. Q: How do I elect to receive PetroCorp stock or a combination of PetroCorp stock and cash in exchange for my Southern Mineral common stock? A: Shortly after the special meetings, each Southern Mineral shareholder will receive a stock election form pursuant to which she may designate the number of shares, if any, she desires to have converted into PetroCorp common stock, subject to possible proration. Q: Can Southern Mineral warrant holders receive PetroCorp stock in the merger? A: Southern Mineral warrant holders can receive PetroCorp stock in connection with the merger only if, prior to the expiration of the merger stock election period, they exercise their warrants (including paying the applicable exercise price) and, as a shareholder, make a valid stock election as provided in the merger agreement. In accordance with the terms of the Southern Mineral warrants, if the merger is completed, PetroCorp will assume each Southern Mineral warrant outstanding immediately prior to the merger and holders of those warrants will be entitled to receive, after payment of the applicable exercise 1 price, for each share of Southern Mineral stock underlying such warrant, the per share merger consideration in cash, without interest. Q: When are the shareholders' meetings? A: Each company's shareholders' meeting will take place on April 25, 2001. The time and location of each meeting is specified on the cover page of this document. Q: What do I need to do to vote? A: Mail your signed proxy card in the enclosed return envelope as soon as possible so that your shares may be represented at your meeting. In order to assure that we obtain your vote, please vote as instructed on your proxy card even if you currently plan to attend your meeting in person. The board of directors of each of Southern Mineral and PetroCorp recommend that Southern Mineral shareholders vote in favor of the merger. Q: When do you expect to complete the merger? A: We expect to complete the merger as quickly as possible once all the conditions to the merger, including obtaining the approvals of our shareholders at the shareholder meetings, are fulfilled or waived. We are required under the merger agreement to complete the merger before May 31, 2001, although we hope to complete it sooner. Q: Should I send in my Southern Mineral stock certificates now? A: No. After the merger is completed, we will send written instructions that will explain how to exchange Southern Mineral stock certificates for cash and/or PetroCorp stock. Please do not send your stock certificates with your proxy. Q: May I change my vote even after returning a proxy card? A: Yes. If you are a Southern Mineral shareholder and want to change your vote, you may do so at any time before the Southern Mineral meeting by sending to the Secretary of Southern Mineral a proxy with a later date. Alternatively, you may revoke your proxy by delivering to the Secretary of Southern Mineral a written revocation prior to the Southern Mineral meeting or by voting in person at the Southern Mineral shareholders meeting. Similarly, if you are a PetroCorp shareholder and want to change your vote, you may do so at any time before the PetroCorp meeting by sending to the Secretary of PetroCorp a proxy with a later date. Alternatively, you may revoke your proxy by delivering to the Secretary of PetroCorp a written revocation prior to the PetroCorp meeting or by voting in person at the PetroCorp meeting. Q: How do I vote my shares if my shares are held in "street name"? A: You should vote this proxy in accordance with the instructions provided to you by your broker. Your broker will not vote your shares unless the broker receives appropriate instructions from you. Q: What happens if I don't vote? A: If a Southern Mineral shareholder does not submit a proxy or vote at the Southern Mineral shareholder meeting, it will have the same effect as a vote against adoption and approval of the merger agreement and approval of the merger. If a PetroCorp shareholder does not submit a proxy or vote at the PetroCorp shareholder meeting, it will not count for purposes of determining if the merger agreement and the merger have been approved. Further, abstentions by shareholders present at the meeting will have the same legal effect as votes against either proposal. 2 Q: If I have more questions about the merger, voting or the two companies, how can I find answers? A: In addition to reading this document and its annexes, you can find more information about the merger or about the two companies in our companies' filings with the SEC and, in the case of PetroCorp, with the AMEX. We incorporate by reference into this document PetroCorp's filings with the SEC. However, we may not and do not incorporate by reference into this document any of Southern Mineral's filings with the SEC. You may also contact Gary R. Christopher at PetroCorp or Michael E. Luttrell at Southern Mineral for additional information. If you have questions about how to submit, revoke or change your proxy, you should contact: .if you are a Southern Mineral shareholder: American Stock Transfer & Trust Company, at (800) 937-5449 .if you are a PetroCorp shareholder: Corporate Stock Transfer, Inc., at (303) 282-4800. 3 SUMMARY This summary highlights selected information from this document and may not contain all of the information that is important to you. To understand the merger more fully, and for a more complete description of the legal terms of the merger, we recommend that you read carefully this entire document and the other available information referred to in "Where You Can Find More Information" on page 102. Each item in this summary includes a page reference directing you to a more complete description of that item. We have included the merger agreement as Annex I to this document. It is the legal document that governs the merger and we encourage you to read it. The Companies (page 81) Southern Mineral Corporation 1201 Louisiana Street, Suite 3350 Houston, Texas 77002 (713) 658-9444 Southern Mineral is an independent oil and gas exploration and production company headquartered in Houston, Texas, and engaged in the acquisition, exploitation, exploration and operation of oil and gas properties, primarily in the Gulf Coast region of the United States, in Canada and in Ecuador. As of December 31, 2000, Southern Mineral had estimated proved reserves of approximately 47.7 billion cubic feet of natural gas and 5.0 million barrels of oil, or an aggregate, on an equivalent basis, of approximately 77.7 billion cubic feet, 85% of which was classified as proved developed. On October 29, 1999, Southern Mineral filed for protection under Chapter 11 of the U.S. Bankruptcy Code, and on August 1, 2000, Southern Mineral emerged from bankruptcy. PetroCorp Incorporated 6733 South Yale Avenue Tulsa, Oklahoma 74136 (918) 491-4500 PetroCorp is an independent oil and gas exploration and production company with reserves and producing properties located in the Gulf Coast and Mid- Continent areas of the United States and in the province of Alberta, Canada. As of December 31, 2000, PetroCorp had estimated proved reserves of approximately 75.3 million cubic feet of natural gas and 4.2 million barrels of oil, or an aggregate, on an equivalent basis, of approximately 100.5 billion cubic feet, 90% of which was classified as proved developed. PetroCorp Acquisition is a wholly-owned subsidiary of PetroCorp recently formed for the sole purpose of effecting the merger. The Merger (page 26) We propose a merger transaction in which Southern Mineral will merge into PetroCorp Acquisition. Southern Mineral shareholders will become PetroCorp shareholders to the extent they receive PetroCorp common stock in exchange for their Southern Mineral common stock. What You Will Receive in the Merger (page 56) In exchange for each share of Southern Mineral stock, each Southern Mineral shareholder will receive merger consideration of $4.71 in cash or, if the shareholder timely elects, in PetroCorp common stock based on an exchange ratio of .471, subject to possible proration as a result of oversubscription for PetroCorp stock as described further beginning on page 56. Each share of PetroCorp common stock will remain issued and outstanding after the merger. Former Southern Mineral shareholders will own between approximately 26% and 32% of the shares of PetroCorp 4 common stock outstanding after the merger, depending on how many stock elections Southern Mineral shareholders make. Election Process for Southern Mineral Shareholders (page 56) If the Southern Mineral and PetroCorp shareholders approve the merger at the special meetings, shortly after the special meetings Southern Mineral shareholders will receive stock election forms pursuant to which they may designate the number of shares they desire to have converted into PetroCorp common stock, subject to proration to the extent Southern Mineral shareholders submit stock election forms to receive more than 4,000,000 shares of PetroCorp stock. Each share of Southern Mineral common stock which has not been designated to be converted into PetroCorp common stock will automatically be converted into the right to receive the per share merger consideration in cash. Shareholders shall have 20 days (or a later date if agreed upon by us prior to mailing stock election forms) from the date the stock elections are mailed to return their stock election forms. We intend to close the transaction promptly after the expiration of the stock election period. In any event, if the merger is not closed by May 31, 2001, either party may terminate the merger agreement. Dissenters' Rights (page 34) Under Nevada law, Southern Mineral shareholders may be entitled to dissenters' rights in connection with the merger. In order to preserve their dissenters' rights, Southern Mineral shareholders must follow strictly the Nevada law regarding dissenters' rights. For further description of these rights, see page 34 and Annex IX, which contains a copy of the Nevada dissenters' statutes. Holders of PetroCorp common stock are not entitled to dissenters' rights in connection with the merger. Material Tax Consequences (page 33) If the merger qualifies as a tax-free reorganization and is consummated, Southern Mineral shareholders generally will not recognize any taxable gain or loss on their exchange of Southern Mineral shares for PetroCorp shares. Southern Mineral shareholders will not know at the time they vote on the merger whether the exchange of their Southern Mineral shares for PetroCorp shares will be subject to tax. A Southern Mineral shareholder will, however, recognize taxable gain or loss on any cash payment received pursuant to the merger. Because shares of PetroCorp common stock will remain unchanged, the merger should not cause a PetroCorp shareholder to recognize any taxable gain or loss for U.S. federal income tax purposes. This tax treatment may not apply to certain shareholders. Determining the actual tax consequences of the merger to you may be complicated. These consequences will depend on your specific situation and on variables not within our control. You should consult your own tax advisor for a full understanding of the merger's tax consequences for you. Accounting Treatment (page 32) The merger will be accounted for under the purchase method for accounting and financial reporting purposes. Management and Operations after the Merger (page 45) After the merger, the combined companies will be known as PetroCorp and will be headquartered in Tulsa, Oklahoma. PetroCorp's day-to-day operations will continue to be managed by employees of Kaiser-Francis Oil Company, PetroCorp's largest shareholder owning 49.7% of PetroCorp's stock as of March 13, 2001, pursuant to a management agreement. 5 PetroCorp's board will expand by two seats to a total of nine members upon the closing of the date of the merger, and Mr. Fuller and Paul J. Coughlin, III, who are currently on the Southern Mineral board, will fill the newly created vacancies and serve at least until PetroCorp's 2003 annual meeting of shareholders. Our Recommendations to Shareholders (pages 28-32) Southern Mineral Shareholders. The members of the Southern Mineral board of directors, each of whom is independent and not otherwise employed by or affiliated with Southern Mineral, unanimously approved the merger and unanimously recommend that you vote FOR the proposal to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger. PetroCorp Shareholders. The members of the PetroCorp board of directors unanimously approved the merger and unanimously recommend that you vote FOR the proposal to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock in connection with the merger. Interests of Officers, Directors and Large Shareholders in the Merger that are Different from Your Interests (page 54) In considering the recommendation of the Southern Mineral or PetroCorp board to vote in favor of the merger, you should be aware that certain officers, directors and large shareholders of Southern Mineral have interests in the merger that may be different from, or in addition to, yours. In particular, we note that if Southern Mineral shareholders elect to receive more than 4,000,000 shares of PetroCorp stock resulting in a proration of the available stock, PetroCorp has agreed to sell up to 108,968 shares in addition to the 4,000,000 shares, to two Southern Mineral directors who have agreed to buy that number of shares equal to their pro rata reduction in connection with their entering into shareholder agreements agreeing to support the merger. In addition, subsequent to the signing of the merger agreement, PetroCorp purchased 738,836 shares of Southern Mineral stock in open-market and negotiated transactions, representing 6.0% of Southern Mineral common stock outstanding as of March 13, 2001. PetroCorp will be able to vote its shares at the Southern Mineral special meeting, but will not be eligible to receive any merger consideration. Opinion of Southern Mineral's Financial Advisor (page 35) On December 22, 2000, Petrie Parkman & Co., Inc., Southern Mineral's financial advisor, delivered to the Southern Mineral board its written opinion as to the fairness from a financial point of view, as of that date and based upon and subject to the matters set forth therein, of the merger consideration to the holders of Southern Mineral common stock. In connection with the Southern Mineral board's approval of the first amendment to the merger agreement, Petrie Parkman confirmed its opinion by delivery of a written opinion to the board dated March 9, 2001. We have attached the opinion dated March 9, 2001 as Annex VIII to this document. We urge you to read this opinion in its entirety to understand the assumptions made and matters considered by Petrie Parkman in rendering its opinion. Petrie Parkman provided its opinions to Southern Mineral's board of directors for its use and benefit and such opinions address only the fairness from a financial point of view as of the dates of the opinions of the merger consideration to the holders of Southern Mineral common stock. The Petrie Parkman opinions are not a recommendation to any Southern Mineral shareholder as to how that shareholder should vote at the special meeting. Special Meetings and Votes Required (pages 78-80) We will hold the Southern Mineral special meeting on April 25, 2001, at 9:00 a.m., local time, at The Doubletree Hotel, 400 Dallas Street, Houston, Texas. We will hold the PetroCorp special meeting on April 25, 2001, at 1:00 p.m., local time, at the Tulsa Room, 9th Floor, Bank of Oklahoma Tower, One Williams Center, Tulsa, Oklahoma. 6 Approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger, requires the approval of the holders of a majority of the outstanding shares of Southern Mineral common stock entitled to vote on the merger. Three directors, solely in their capacity as shareholders of Southern Mineral, are parties to shareholder agreements pursuant to which they have agreed to vote their 2,239,618 shares of Southern Mineral common stock in favor of the merger, representing approximately 18.3% of the shares of Southern Mineral common stock outstanding as of the record date for voting at the special meeting. Approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock, requires approval by the holders of a majority of all outstanding shares of PetroCorp common stock present (in person or by proxy) at a meeting at which a quorum is present. PetroCorp is seeking a majority shareholders approval of the transaction as required by AMEX rules which provide that a company issuing common stock in an amount which could result in an increase in outstanding common shares of 20% or more must have approval of a majority of PetroCorp shares represented (in person or by proxy) at a meeting at which a quorum exists. Two large shareholders are parties to shareholder agreements pursuant to which they have agreed to vote their 6,065,457 outstanding shares of PetroCorp common stock in favor of the merger, representing approximately 69.6% of the shares of PetroCorp common stock outstanding as of the record date for voting at the special meeting. Because 69.6% of the outstanding shares of PetroCorp have agreed to vote for the merger, approval of the merger by PetroCorp's shareholders at the special meeting is assured. Overview of the Merger Agreement (pages 56-62) We have included the merger agreement as Annex I to this document. It is the legal document that governs the merger and we encourage you to read it. Conditions to the Merger (page 60) We will complete the merger only if a number of conditions are satisfied or waived including, among others: .PetroCorp's and Southern Mineral's shareholders approve the merger agreement; .Southern Mineral shareholders elect to receive at least 3,000,000 PetroCorp shares in the merger; . the representations and warranties contained in the merger agreement are accurate, except insofar as the inaccuracy would not have a materially adverse effect, and the parties have fulfilled in all material respects their covenants and other agreements; .no law, rule, regulation or court order prohibits the merger; . there has been no change that would have a material adverse effect on either Southern Mineral or PetroCorp; and .all necessary consents from third parties have been obtained. No Solicitation (page 60) Southern Mineral has agreed not to initiate any discussions with another party regarding a business combination while the merger is pending. Termination of the Agreement (pages 61-62) Southern Mineral and PetroCorp may, by mutual agreement, terminate the merger agreement at any time, even after the shareholders have approved the merger. In addition, either party may terminate the agreement: .if the other party is in material breach of the merger agreement; .if a statute, rule, court order, regulation or executive order permanently prohibits the merger; 7 . if either the PetroCorp or Southern Mineral shareholders fail to approve the merger at a duly held meeting of shareholders; or .if the merger has not been consummated on or before May 31, 2001. In addition, Southern Mineral has the right to terminate the merger agreement if the Southern Mineral board has received a superior proposal which it has resolved to accept. PetroCorp may terminate the merger agreement if the Southern Mineral board fails to reject a superior proposal within 30 days of receipt. Termination Fees (page 62) If Southern Mineral terminates the merger agreement because it is accepting a superior proposal, it is required to pay PetroCorp $2,350,000. PetroCorp will pay Southern Mineral $250,000 if the merger does not occur for any reason other than: . a breach by Southern Mineral of its representations, warranties, covenants or obligations under the merger agreement; . Southern Mineral shareholders failing to approve the merger at a duly held meeting of shareholders; . Southern Mineral or PetroCorp having a material adverse change in their financial conditions, businesses or operations; . Southern Mineral not obtaining the necessary consents and waivers to consummate the merger; or . PetroCorp electing to terminate the merger agreement because the Southern Mineral board has not rejected a superior proposal within 30 days of receipt. Either of us may choose to complete the merger even though a condition has not been satisfied if applicable law allows us to do so. Regulatory Approvals (page 32) Neither Southern Mineral nor PetroCorp is aware of a material governmental or regulatory approval required for completion of the merger, other than compliance with applicable laws. 8 COMPARATIVE PER SHARE MARKET PRICE AND DIVIDEND INFORMATION PetroCorp's shares are listed on the AMEX under the symbol "PEX" and Southern Mineral's shares are quoted on the OTC Bulletin Board under the symbol "SMOP.OB." On December 21, 2000, the last trading day before we announced the merger, PetroCorp's shares closed at $9.875 per share and Southern Mineral's shares closed at $3.125 per share. On March 27, 2001, the most recent practicable date before the mailing of this document, PetroCorp's shares closed at $9.85 per share and Southern Mineral's shares closed at $4.30 per share. Based on an exchange ratio in the merger of .471 shares of PetroCorp common stock per share of Southern Mineral common stock, the market value of the consideration that Southern Mineral shareholders will receive in the merger for shares of PetroCorp common stock would be $4.65 based on the closing price of shares of PetroCorp on December 21, 2000, and $4.64 per share based on the closing price of shares of PetroCorp common stock on March 27, 2000. Of course, the market price of shares of PetroCorp will fluctuate prior to and after the merger, whereas the exchange ratio is fixed. See page 18 with regard to risk factors related to this fluctuation. You should obtain current stock price quotations for PetroCorp and Southern Mineral common stock. Historical Market Prices of PetroCorp and Southern Mineral The following table sets forth the high and low trading prices per share of PetroCorp common stock on the AMEX and the Southern Mineral common stock on the OTC Bulletin Board and, prior to August 4, 1999, the Nasdaq National Market. High and low prices for Southern Mineral stock have been adjusted to reflect a five for one reverse split effected on August 1, 2000. PetroCorp Southern Mineral Common Stock Common Stock ------------ ----------------- High Low High Low ------ ----- -------- -------- 1999 First Quarter................................... $ 5.88 $5.19 $ 5.00 $ 1.25 Second Quarter.................................. $ 6.13 $4.38 $ 2.95 $ 1.55 Third Quarter................................... $ 7.50 $5.50 $ 2.65 $ 1.10 Fourth Quarter.................................. $ 6.88 $5.75 $ 1.70 $ 0.45 2000 First Quarter................................... $ 6.75 $5.25 $ 2.42 $ 0.78 Second Quarter.................................. $ 7.25 $5.50 $ 3.13 $ 0.78 Third Quarter................................... $ 9.88 $7.00 $ 4.19 $ 2.73 Fourth Quarter.................................. $10.19 $8.63 $ 4.00 $ 2.91 2001 First Quarter (through March 27)................ $10.75 $9.62 $ 4.33 $ 3.88 No History of Dividends and No Dividends Expected in the Foreseeable Future Neither PetroCorp nor Southern Mineral is currently paying dividends on its common stock. After the merger, PetroCorp expects that it will retain all available earnings generated by its operations for the development and growth of the business. Therefore, PetroCorp does not anticipate paying cash dividends on its common stock in the foreseeable future. The debt instruments of both PetroCorp and Southern Mineral limit their ability to pay dividends on their common stock. 9 SUMMARY SELECTED HISTORICAL CONSOLIDATED FINANCIAL DATA We are providing the following financial information to aid you in your analysis of the financial aspects of the merger. This information is only a summary and you should read it together with the historical consolidated financial statements of PetroCorp and Southern Mineral and the related notes in this prospectus, and the historical consolidated financial statements of PetroCorp incorporated by reference in this document and delivered as part of Annex XI with this prospectus. The historical financial information reflects the following items that you should consider in making period-to-period comparisons: PetroCorp . On August 3, 1999, as part of a restructuring plan, PetroCorp entered into its management agreement with Kaiser-Francis. As a result of the restructuring, PetroCorp terminated 52 employees in 1999 and one employee in 2000, but several employees terminated in 1999 elected to defer receipt of their termination benefits until 2000. In addition, PetroCorp closed its Houston, Oklahoma City and Calgary offices. Southern Mineral . On October 29, 1999, Southern Mineral and its wholly-owned subsidiaries (other than Southern Mineral's Canadian subsidiary, Neutrino Resources, Inc.) filed voluntary petitions for relief under Chapter 11, Title 11 of the United States Code, in order to facilitate the restructuring of Southern Mineral's long-term debt, revolving credit, trade debt and other obligations. Southern Mineral and its subsidiaries emerged from bankruptcy on August 1, 2000. All debts of Southern Mineral, except those of Neutrino, as of October 29, 1999 were stayed by the bankruptcy petitions, and were subject to compromise pursuant to such proceedings until August 1, 2000. Southern Mineral operated as a debtor-in-possesion subject to the bankruptcy court's supervision and orders. . Weighted average shares outstanding and per share calculations have been adjusted to reflect the five for one reverse split of Southern Mineral stock effected on August 1, 2000. 10 PetroCorp Incorporated For the Year Ended December 31, ------------------------------------------------ 2000 1999 1998 1997 1996 -------- -------- -------- -------- -------- (in thousands, except per share data) Statement of Operations Data: Revenues: Oil and gas................. $ 42,264 $ 25,162 $ 23,621 $ 33,502 $ 29,718 Plant processing............ 1,934 1,785 1,550 1,420 1,658 Other....................... 375 179 36 172 170 -------- -------- -------- -------- -------- 44,573 27,126 25,207 35,094 31,546 -------- -------- -------- -------- -------- Expenses: Production costs............ 8,038 6,733 7,344 7,793 6,660 Depreciation, depletion and amortization 9,471 9,906 16,568 17,065 12,433 Oil and gas property valuation adjustment -- -- 33,600 -- -- General and administrative.. 1,529 4,311 4,482 4,846 4,542 Restructuring costs.........

The pro forma combined income statement data gives effect to the merger as if it occurred on January 1, 2000. This information does not necessarily indicate what the future operating results or financial position of the combined company will be.

You should read the table together with the financial information for PetroCorp and Southern Mineral included in this document. Please also note that we computed: . the historical book value per share amounts by dividing each company's shareholders' equity by its actual common shares outstanding as of December 31, 2000; . the pro forma combined book value per share amounts by dividing pro forma shareholders' equity by the pro forma number of common shares of PetroCorp outstanding as of December 31, 2000, assuming the merger occurred on that date; . the pro forma combined per Southern Mineral equivalent share amounts by multiplying the pro forma combined share amounts by the exchange ratio of .471 for each share of Southern Mineral common stock; and . Southern Mineral per share calculations to reflect the five for one reverse split of Southern Mineral stock effected on August 1, 2000. The pro forma comparative per share data, which is derived from the Unaudited Pro Forma Combined Financial Statements and notes thereto beginning on page F-2, does not purport to represent the results that PetroCorp would have achieved if the merger had taken place earlier or of the results of operations of PetroCorp after the merger.

It represents the present value of the estimated future net cash flows before income taxes and general administrative overhead and has not been adjusted for outstanding loans that may exist or cash on hand or undistributed income. These future net cash flows are discounted at a rate of 10% per annum.

In addition, you should pay particular attention to the following risks related to the merger and the combined company. Risks Relating to the Merger The per share merger consideration will not be adjusted due to changes in the price of PetroCorp or Southern Mineral common stock, and as a result, Southern Mineral shareholders receiving stock may receive less value for their shares. In exchange for each share of Southern Mineral stock, Southern Mineral shareholders will receive merger consideration of $4.71 in cash or, if the shareholder timely elects, in PetroCorp common stock based on an exchange ratio of .471, subject to proration as described in "The Merger Agreement -- Southern Mineral Stock Elections; Minimum and Maximum Share Issuances" on page 56. The exchange ratio will not be adjusted as a result of any decrease or increase in the price of PetroCorp common stock. Therefore, because the market price of PetroCorp common stock is subject to fluctuation, the value at the time of the merger of the consideration to be received by the Southern Mineral shareholders that make valid stock elections will depend on the market price of PetroCorp common stock at that time and may be lower than the market price of PetroCorp common stock on the date of this document or the date of the special meetings. The business, operations or prospects of PetroCorp, regulatory considerations, general market and economic conditions and other factors may affect the price of PetroCorp common stock. Most of those factors are beyond our control. You are encouraged to obtain current market quotations for PetroCorp common stock. For historical and current market prices of PetroCorp common stock, see "Comparative Per Share Market Price and Dividend Information" on page 9. We may not realize the benefits of integrating our companies. Integrating our businesses involves a number of risks, including: . the possibility that management may be distracted from regular business concerns by the need to integrate operations; . unforeseen difficulties in integrating operations and systems; and . the possibility that Kaiser-Francis may not be able to assume all employee and management responsibilities for the business and assets of the combined company pursuant to the PetroCorp management agreement discussed on page 97. Any of these could lead to potential adverse short-term or long-term effects on operating results. As a result, we may not realize any of the anticipated benefits of the merger. We have incurred and will incur charges and expenses as a result of the merger, which must be paid even if the merger fails to close. PetroCorp and Southern Mineral expect to incur approximately $3.5 million of costs related to the merger, including severance and retention bonuses payable to Southern Mineral employees upon completion of merger totaling $1,357,124, investment banking expenses, legal and accounting fees, printing expenses, transition and integration costs and other related charges. See "Interests of Certain Persons in the Merger -- Southern Mineral" on page 54. The companies may also incur additional unanticipated expenses in connection with the merger. Southern Mineral and PetroCorp will have to pay all merger related costs and expenses, other than retention and severance bonuses and investment banking fees, even if the merger does not close. 18 Some directors, officers and affiliates of the companies have interests in the merger that are different from your interests which may make them more likely to recommend approval of the merger. Two directors of Southern Mineral, Messrs. Fuller and Wiese, are parties to agreements that allow them to purchase up to 108,968 shares of PetroCorp stock to the extent of any pro rata reduction in their stock elections. In addition, Messrs. Fuller and Coughlin will be elected to serve on the PetroCorp board until PetroCorp's 2003 annual meeting, and will be eligible for compensation from PetroCorp for that service. See "Interests of Certain Persons in the Merger -- Southern Mineral" on page 54. Also, in August 1999, Kaiser-Francis, the majority shareholder of PetroCorp, and PetroCorp entered into a management agreement under which Kaiser-Francis agreed to provide management, technical and administrative support for all of PetroCorp's operations in the United States and Canada. In the event of the merger, Kaiser-Francis will assume these same management functions for the combined company, for which it will receive additional revenue. In addition, Steve Berlin, an officer of PetroCorp, owned 15,000 Southern Mineral shares as of the record date for voting at the special meeting, and Craig Dolinsky, also an officer of PetroCorp, owned 5,000 Southern Mineral shares as of the record date for voting at the special meeting. See "Interests of Certain Persons in the Merger -- PetroCorp" on page 54. As a result of these interests, Southern Mineral directors and PetroCorp officers and directors affiliated with Kaiser-Francis could be more likely to support or recommend approval of the merger agreement and the merger than if they did not have these interests. Southern Mineral and PetroCorp shareholders should consider whether these interests may have influenced these officers and directors to support or recommend the approval of the merger agreement and the merger. Risks Related to PetroCorp after the Merger It may be difficult for PetroCorp to replace Kaiser-Francis if PetroCorp desires to terminate the Kaiser-Francis management agreement or Kaiser-Francis terminates the agreement. PetroCorp has no employees, and all of its technical and corporate services are provided by Kaiser-Francis pursuant to a management agreement. As a result, PetroCorp does not have full control over its operations. Either PetroCorp or Kaiser-Francis may terminate the Kaiser-Francis management agreement at any time upon six months notice. If the agreement is terminated, and if we are unable to engage third parties to perform these services and have to replicate facilities, services or employees that we are not using fulltime, or are not able to engage a third party at costs similar to those charged by Kaiser- Francis, PetroCorp's costs would increase. PetroCorp may not be able to find another contractor to provide substantially similar services at the same rates or replicate such services without incurring additional costs. Kaiser-Francis and its affiliates may have conflicts of interest with us and, accordingly, you. Kaiser-Francis, PetroCorp's largest shareholder, and its subsidiaries explore for and produce oil and gas in some of the same geographic areas in which we operate. Kaiser-Francis is not required to pursue a business strategy that will favor PetroCorp business opportunities over the business opportunities of Kaiser-Francis, its affiliates, or any other competitor of PetroCorp acquired by Kaiser-Francis. In fact, Kaiser-Francis may have financial motives to favor itself. In addition, because of PetroCorp's management agreement with Kaiser- Francis, PetroCorp, Kaiser-Francis and its affiliates share, and therefore will compete for, the time and effort of Kaiser-Francis personnel who provide services to PetroCorp. Officers of Kaiser-Francis and its affiliates do not, and will not be required to, spend any specified percentage or amount of time on our business. Since these shared officers function as both PetroCorp representatives and those of Kaiser-Francis and its affiliates, conflicts of interest could arise between Kaiser-Francis and its affiliates, on the one hand, and PetroCorp or you, on the other. See "The Companies -- PetroCorp -- PetroCorp's Management Agreement with Kaiser-Francis" on page 98. 19 Oil price declines and volatility could adversely affect our revenues, cash flows and profitability. PetroCorp's revenues, profitability and future rate of growth depend substantially upon the prevailing prices of oil and gas. Because approximately 74.9% of our pro forma estimated proved reserves as of December 31, 2000 were natural gas reserves, our financial results are more sensitive to movements in natural gas prices. Natural gas and oil and are commodities and, therefore, their prices are subject to wide fluctuations in response to relatively minor changes in supply and demand these changes may arise from: . weather conditions, . the ability of the members of OPEC to agree to and maintain oil price and production controls, . political instability or armed conflict in oil-producing regions, . the price and availability of alternative fuels, . the availability of pipeline capacity, and . domestic and foreign governmental regulations and taxes. Historically, the markets for natural gas and oil have been volatile, and they are likely to continue to be volatile in the future. For example, natural gas and oil prices declined significantly in late 1997, 1998, and early 1999, and, for an extended period of time, remained substantially below prices obtained in previous years. Southern Mineral's inability to satisfy its debt obligations in 1999 was in part a result of this decline in oil prices and ultimately led Southern Mineral to file for bankruptcy protection in October 1999. Lower oil and gas prices may reduce the amount of oil and gas PetroCorp produces. Significant reductions in oil and gas prices may require PetroCorp to reduce its capital expenditures. Reducing drilling will make it more difficult for PetroCorp to replace the reserves it produces. If PetroCorp is not able to replace reserves, it may not be able to sustain current production rates. PetroCorp's future success depends largely upon its ability to find, develop or acquire additional oil and gas reserves that are economically recoverable. Unless PetroCorp replaces the reserves it produces through successful development, exploration or acquisition, its proved reserves will decline over time. In addition, approximately 10% by volume of its total estimated proved reserves at December 31, 1999, and 16% by volume of Southern Mineral's total estimated proved reserves at December 31, 1999 were undeveloped. By their nature, undeveloped reserves are less certain. Recovery of such reserves will require significant capital expenditures and successful drilling operations. PetroCorp may fail to successfully find and produce reserves economically in the future. PetroCorp's increased reserve base will make it more difficult to find exploration and acquisition opportunities to replace production. Drilling levels required to replace reserves will likely increase PetroCorp's exposure to drilling risk. If PetroCorp does not make significant capital expenditures, it may not be able to exploit reserves. PetroCorp must make substantial capital expenditures in connection with the exploration, development and production of its oil and gas properties. PetroCorp anticipates that its oil and gas capital expenditures for the combined company will be approximately $6 million for drilling and recompletion activity in 2001. PetroCorp intends to finance its capital expenditures primarily with funds provided by operations and borrowings under its credit agreement, to be supplemented from time to time with funds obtained from additional equity offerings. If PetroCorp's cash flow from operations and availability under existing credit facilities are not sufficient to 20 satisfy capital expenditure requirements, additional debt or equity financing may not be available to allow it to fund its continued growth. PetroCorp will utilize up to approximately $10 million of the total $29.5 million available at December 31, 2000, under its existing credit facility to effect the merger. PetroCorp has a $75 million credit facility with a current borrowing base limitation of $58 million. PetroCorp's industry experiences numerous operating risks. Insurance may not be adequate to protect PetroCorp against all these risks. Oil and gas drilling and production activities are subject to numerous risks, including the risk that no commercially productive oil and gas reserves will be found. The cost of drilling and completing wells is often uncertain. Oil and gas drilling and production activities may be shortened, delayed or canceled as a result of a variety of factors, many of which are beyond our control, including: . pressure or irregularities in formations; . equipment and materials failures or accidents; . blowouts and surface cratering; . fires and explosions; . uncontrollable flows of oil and formation water; and . environmental hazards such as oil spills, pipeline ruptures and discharges of toxic gases. If any of these events occur, we could incur substantial losses as a result of: . injury or loss of life; . severe damage to and destruction of property, natural resources and equipment; . pollution and other environmental damage; . regulatory investigation and penalties; . suspension of our operations; and . repairs to resume operations. Our insurance does not protect us against all operational risks. We do not carry business interruption insurance at levels that would provide enough funds for us to continue operating without access to other funds. For some risks, we may not obtain insurance if we believe the cost of available insurance is excessive relative to the risks presented. Because third party drilling contractors are used to drill our wells, we not may not realize the full benefit of workmen's compensation laws in dealing with their employees. In addition, pollution and environmental risks generally are not fully insurable. PetroCorp's articles of incorporation, bylaws and rights plan discourage corporate takeovers and could prevent shareholders from realizing a premium on their investment. PetroCorp's articles of incorporation and bylaws and provisions of the Texas Business Corporation Act may have the effect of delaying or preventing a change in control. PetroCorp's directors are elected to staggered terms. Also, PetroCorp's articles of incorporation authorize PetroCorp's board of directors to issue preferred stock without shareholder approval and to set the rights, preferences and other designations, including voting rights of those shares as the board may determine, and PetroCorp has available authorized but unissued common stock. In addition, PetroCorp has adopted a rights plan, as further described on page 77, which could, alone or in combination with the articles of incorporation and the bylaws, discourage transactions involving actual or potential changes of control, including transactions that otherwise could involve payment of a premium over prevailing market prices to shareholders for their common stock. 21 Reserve estimates depend on many assumptions that may turn out to be inaccurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and net present value of our reserves. The calculations of proved reserves of oil and gas included in this document have been prepared by independent petroleum engineers retained by PetroCorp and Southern Mineral. The accuracy of any reserve estimate is a function of the quality of available data, engineering and geological interpretations and judgment and the assumptions used regarding quantities of recoverable oil and natural gas reserves and prices for crude oil and natural gas. Any significant variance between the assumptions used in our estimates and the actual data could result in the actual quantity of our reserves and future net cash flow being materially different from the estimates in our reserve reports. In addition, results of drilling, testing and production and changes in crude oil and natural gas prices after the date of the estimate may result in substantial upward or downward revisions. Also, we may adjust estimates of proved reserves to reflect production history, results of exploration and development, prevailing natural gas and oil prices and other factors, many of which are beyond our control. At December 31, 2000, 10 percent of our pro forma proved reserves were proved undeveloped or proved non-producing. Further, because most of our reserve estimates are not based on a lengthy production history and are calculated using volumetric analysis, these estimates are less reliable than estimates based on a lengthy production history. You should not assume that the present value of future net cash flows from our proved reserves included or incorporated by reference in this prospectus is the current market value of our estimated natural gas and oil reserves. In accordance with SEC requirements, we base the estimated discounted future net cash flows from our proved reserves on prices and costs on the date of the estimate, which may vary materially from actual future prices and costs. PetroCorp may be unable to identify liabilities associated with the properties that it acquires or obtain protection from sellers against them. The successful acquisition of producing properties involves an assessment of recoverable reserves, future oil and gas prices, operating costs, potential environmental and other liabilities and other factors beyond PetroCorp's control. This assessment is inexact and uncertain. In connection with this assessment, PetroCorp will perform a review of the subject properties, but this review will not reveal all existing or potential problems. Inspections may not be performed on every well, and structural and environmental problems are not necessarily observable even when an inspection is undertaken. PetroCorp may in many cases assume pre-closing liabilities, including environmental liabilities, and will likely acquire interests in properties on an "as is" basis. PetroCorp's acquisitions may be unsuccessful. The failure of PetroCorp to successfully complete acquisitions could have a material adverse effect on PetroCorp. Hedging activities could result in losses to PetroCorp. PetroCorp and Southern Mineral use, and it is expected that PetroCorp will continue to use, energy swap arrangements and financial futures to reduce sensitivity to oil and gas price volatility. If PetroCorp's reserves are not produced at the rates estimated by PetroCorp due to inaccuracies in the reserve estimation process, operational difficulties or regulatory limitations, PetroCorp will be required to satisfy obligations it may have under fixed price sales and hedging contracts on potentially unfavorable terms without the ability to hedge that risk through sales of comparable quantities of its own production. Further, the terms under which PetroCorp enters into fixed price sales and hedging contracts are based on assumptions and estimates of numerous factors such as cost of production and pipeline and other transportation costs to delivery points. Substantial variations between the assumptions and estimates used and actual results experienced could materially adversely affect anticipated profit margins and PetroCorp's ability to manage the risk associated with fluctuations in oil and gas prices. 22 Additionally, fixed price sales and hedging contracts limit the benefits PetroCorp will realize if actual prices rise above the contract prices. Based upon prices in effect at December 31, 2000, the fair value (loss) of Southern Mineral's crude oil and natural gas hedging instruments were unrealized losses of $3.2 million. PetroCorp had no hedging contracts at December 31, 2000. In addition, fixed price sales and hedging contracts are subject to the risk that the counter-party may prove unable or unwilling to perform its obligations under these contracts. Any significant nonperformance could have a material adverse financial effect on PetroCorp. PetroCorp's significant indebtedness could have important adverse consequences to you. After the merger PetroCorp will have a substantial amount of indebtedness. At December 31, 2000, on a pro forma basis with 4,108,968 shares issued, PetroCorp's total long-term debt outstanding would have been approximately $46.8 million and PetroCorp would have had a long-term debt to total capitalization ratio of 50 percent. Based on 3,000,000 shares issued, PetroCorp's total long-term debt outstanding would be $56.8 million and its long-term debt to total capitalization ratio would be 68 percent as of December 31, 2000. PetroCorp may incur additional indebtedness under PetroCorp's credit facility. Additionally, the merger agreement provides that PetroCorp shall pay off debt under Southern Mineral's credit facilities which, as of December 31, 2000, equaled $16.8 million. After the merger, repaying this debt may be refinanced under PetroCorp's existing credit facility. Our significant indebtedness could have important consequences to you. For example: . PetroCorp's ability to obtain any necessary financing in the future for working capital, capital expenditures, acquisitions, debt service requirements or other purposes may be limited; . a portion of PetroCorp's cash flow from operations must be utilized for the payment of interest on PetroCorp's indebtedness and will not be available for financing capital expenditures or other purposes; . PetroCorp's level of indebtedness and the covenants governing PetroCorp's current indebtedness could limit PetroCorp's flexibility in planning for, or reacting to, changes in PetroCorp's business because financing options may be limited or prohibited; . PetroCorp's level of indebtedness may make PetroCorp more vulnerable during periods of low oil and gas prices or in the event of a downturn in PetroCorp's business because of PetroCorp's fixed debt service obligations; and . if the requirements of PetroCorp's credit facilities are not satisfied, the lenders under these facilities would be entitled to accelerate the payment of all outstanding indebtedness under this facility and, in such event, PetroCorp may not have sufficient funds available, or may not be able to obtain the financing required, to meet its obligations. Costs to comply with environmental laws are significant. Environmental and other governmental laws, some of which are applied retroactively, have increased the costs to plan, design, drill, install, operate and abandon oil and natural gas wells and related facilities. We may be required to make large expenditures to comply with environmental laws. Under these laws and regulations, we could be liable for personal injuries, property damage, oil spills, discharge of hazardous materials, remediation and clean-up costs and other environmental damages. We do not believe that full insurance coverage for all potential environmental damages is available at a reasonable cost. Failure to comply with these laws and regulations also may result in the suspension or termination of our operations and subject us to administrative, civil and criminal penalties. Moreover, these laws and regulations could change in ways that substantially increase our costs. For example, Congress or the Minerals Management Service could decide to limit exploratory drilling or natural gas production in some areas of the Gulf of Mexico. Accordingly, any of these liabilities, penalties, suspensions, terminations or regulatory changes could materially and adversely affect our financial condition and results of operations. 23 Marketability of PetroCorp's production may be affected by factors beyond its control. The marketability of PetroCorp's production depends in part upon the availability, proximity and capacity of oil and gas gathering systems, pipelines and processing facilities. Most of PetroCorp's oil and gas will be delivered through gathering systems and pipelines that are not owned by PetroCorp. Federal and state regulation of oil and gas production and transportation, tax and energy policies, changes in supply and demand and general economic conditions all could adversely affect PetroCorp's ability to produce and market its oil and gas. A small number of shareholders will control PetroCorp, making it difficult for other PetroCorp shareholders to affect PetroCorp's management. Upon completion of the merger, directors, executive officers and principal shareholders of PetroCorp, and their affiliates, will beneficially own approximately . 63.4% of PetroCorp's outstanding common stock, including 37.0% owned by Kaiser-Francis, if 3,000,000 shares of PetroCorp stock are issued in the merger, and . 58.3% of PetroCorp's outstanding common stock, including 34.1% owned by Kaiser-Francis, if 4,000,000 shares of PetroCorp stock are issued in the merger. Accordingly, these shareholders, as a group, will be able to control the outcome of shareholder votes, including votes concerning the election of directors, the adoption or amendment of provisions in PetroCorp's articles of incorporation or bylaws, and the approval of mergers and other significant corporate transactions. The existence of these levels of ownership concentrated in a few persons makes it unlikely that any other holder of PetroCorp common stock will be able to affect the management or direction of PetroCorp. These factors may also have the effect of delaying or preventing a change in the management or voting control of PetroCorp, including transactions that otherwise could involve payment of a premium over prevailing market prices to holders of PetroCorp common stock. Future sales of PetroCorp common stock may result in a decrease in value to existing shareholders. After the merger, assuming no additional issuances of common stock prior to the merger, PetroCorp will have between approximately 11,703,719 and 12,812,687 shares of common stock outstanding. Of those shares, from approximately 8,224,509 to 9,224,509 shares of common stock will be freely transferable without restriction except with regard to certain transactions by affiliates. Future sales of substantial amounts of common stock, or the perception that these sales could occur, may affect the market price of our common stock. PetroCorp does not expect to pay dividends on its common stock. After the merger, PetroCorp expects that it will retain all available earnings generated by its operations for the development and growth of the business. Therefore, PetroCorp does not anticipate paying cash dividends on its common stock in the foreseeable future. PetroCorp's debt instruments limit its ability to pay dividends on its common stock. 24 FORWARD-LOOKING STATEMENTS This document includes "forward-looking statements" made by PetroCorp within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934.

Consistent will PetroCorp's strategy, Mr. Christopher, President and Chief Executive Officer of PetroCorp, contacted Steven H. Mikel, President and Chief Executive Officer of Southern Mineral, in October 1999 and requested that Mr. Mikel consider a merger of Southern Mineral into PetroCorp. PetroCorp executed a Confidentiality Letter dated October 11, 1999, and Southern Mineral forwarded its most current reserve reports to PetroCorp at that time. After Southern Mineral filed a bankruptcy petition on October 29, 1999, Mr. Christopher and Mr. Mikel spoke and decided to suspend any discussion of a merger until Southern Mineral had worked further into its bankruptcy proceedings. On June 27, 2000, PetroCorp sent a letter to the Southern Mineral board, which expressed PetroCorp's intent to work toward a purchase of Southern Mineral or combination with Southern Mineral as one potential avenue for the reorganization of Southern Mineral. Southern Mineral was in the midst of negotiating a reorganization arrangement with its principal creditors, and proceeded to finalize negotiations with its creditors rather than seek a combination with PetroCorp within the bankruptcy case. Southern Mineral and its creditors reached a negotiated reorganization arrangement in early July 2000. On August 1, 2000, Southern Mineral successfully emerged from bankruptcy with a restructured balance sheet and a reorganized board of directors. The terms of the reorganization called for the holders of Southern Mineral's debentures to exchange the debentures for 78% of the common equity of Southern Mineral with the remaining 22% to go to prior equity owners of Southern Mineral. Shareholders, option holders and warrant holders of record on July 24, 2000, received approximately 3,667,000 warrants allowing them to increase their ownership from 22% to up to 40% of the outstanding common stock. The Series B warrants issued in the bankruptcy reorganization are for a perpetual term with an exercise price of $4.21 per share, subject to adjustment for certain customary anti-dilution events, such as stock splits, stock dividends and other recapitalization events. Southern Mineral's board was restructured, with five of seven new members being appointed by the creditors' committee or by large former debenture holders. On August 9, 2000, the newly restructured Southern Mineral board met with representatives of Petrie Parkman and FirstEnergy Capital Corp. At that meeting, the board directed management to engage the services of Petrie Parkman and FirstEnergy Capital as financial advisors to evaluate strategies to maximize shareholder value. Petrie Parkman was directed to undertake an evaluation of strategic alternatives available to Southern Mineral, and FirstEnergy Capital was directed to evaluate strategies related to Neutrino Resources, Southern Mineral's wholly-owned Canadian subsidiary, in connection with a possible stand-alone Canadian transaction. Petrie Parkman identified and provided to Southern Mineral a list of companies, including PetroCorp, that might offer Southern Mineral one or more strategic opportunities, including joint ventures, mergers, acquisitions and divestitures. After further review, Petrie Parkman was authorized and directed to contact various companies, including PetroCorp, to determine their type and level of interest in a possible transaction involving Southern Mineral. Based on the information received from such companies, Southern Mineral directed Petrie Parkman to conduct a more extensive inquiry and request the most desirable candidates to deliver written expressions of interest. Of the 44 companies Petrie Parkman contacted, 12 companies completed a review in a data room set up by Southern Mineral and Petrie Parkman, and six companies, including PetroCorp, made either written or oral expressions of interest to merge with or acquire Southern Mineral. On October 11, 2000, representatives of FirstEnergy Capital made presentations regarding the Canadian process to the Southern Mineral board and representatives of Petrie Parkman made a presentation regarding the status of the U.S. process. Based upon the progress of discussions with interested parties being conducted by Petrie Parkman, the board determined that it was in the best interests of Southern Mineral and its shareholders to attempt to merge with one company. As a result, the FirstEnergy Capital-led process to evaluate strategies related to Nuetrino Resources was given secondary status as it would require two transactions to sell or merge Neutrino Resources and then to sell or merge Southern Mineral. 26 Southern Mineral's board determined that the written expression of interest received from PetroCorp on September 6, 2000, proposing a merger, provided one of the more desirable potential transactions. PetroCorp's offer was to merge Southern Mineral into PetroCorp. It appeared the combined company would possess operating efficiencies and complementary geographical asset bases that were attractive to the Southern Mineral board. On October 19, 2000, Mr. Christopher met with representatives of Petrie Parkman and with Michael E. Luttrell, chief financial officer of Southern Mineral, and Mr. Mikel at the offices of Petrie Parkman in Houston. Mr. Christopher described in more detail the businesses and goals of PetroCorp. Mr. Christopher also discussed the oil and gas business in general and the possibility of, among other things, combining Southern Mineral and PetroCorp in the future to create a larger independent public oil and gas company with more potential growth prospects and access to capital markets. The parties agreed to explore the possibility of such a transaction and agreed to exchange further information with each other. Mr. Christopher also discussed PetroCorp's management contract with Kaiser Francis, and indicated that following the merger PetroCorp would terminate the management and staff of Southern Mineral. The parties discussed in detail their respective properties, financial position, objectives and philosophies. The parties agreed to enter into discussions regarding a proposed merger structure and to conduct further due diligence investigations. During the final weeks of October and into early November, there were general discussions regarding proposed structures and merger consideration. On November 8, 2000, PetroCorp submitted a revised proposal to Southern Mineral to merge in exchange for stock and cash. On November 10, 2000, the Southern Mineral board again met with representatives of FirstEnergy and Petrie Parkman to discuss the status of current efforts relative to their respective engagements. During the meeting, Petrie Parkman discussed with the board of directors a revised stock and cash proposal from PetroCorp dated November 9, 2000, together with five other oral or written proposals. Of the six expressions of interest, PetroCorp's was most attractive because it provided for a merger of all of Southern Mineral into PetroCorp. Three of the other expressions indicated a preference for only U.S. assets. The board considered the other two remaining merger proposals to be less favorable than the PetroCorp written proposal because the other two merger proposals offered less merger consideration and did not offer a combination of stock and cash, a feature the Southern Mineral board found attractive. Following a general discussion, the board directed management and Petrie Parkman to focus most of their efforts on discussions with the management and board of PetroCorp. Following the board meeting on November 10, 2000, representatives of Petrie Parkman held several telephonic discussions with Mr. Christopher and his associates regarding possible structures for a combination. Thereafter, Petrie Parkman, at the direction of Southern Mineral, informed other potential counterparties that Southern Mineral had decided to focus on one transaction, but that they might be contacted again if discussions did not result in a satisfactory transaction. On November 24, 2000, PetroCorp sent a letter of intent directed to Petrie Parkman, as Southern Mineral's financial advisor. The letter of intent was not as favorable to Southern Mineral's shareholders as the terms of the final definitive agreements. It included the following material terms: . a merger consideration per Southern Mineral share of $4.51, compared with the final per share merger consideration of $4.71; . additional adjustments to the merger consideration not included in the final agreements; and . additional conditions to closing not included in the final agreements which the Southern Mineral board was not certain would be satisfied. Nevertheless, the November 24 letter provided a framework for further discussion. On November 28, 2000, Mr. Mikel transmitted a response to Mr. Christopher's letter of November 24, 2000, outlining numerous deal points that he felt would be required before the Southern Mineral board would be willing to commit Southern 27 Mineral's time and resources to any further discussions, analysis and negotiations. On November 30, 2000, Mr. Christopher and Mr. Mikel and their associates, and representatives of Petrie Parkman held a conference call concerning several aspects of the transaction structure, including the amount of stock and cash consideration. During the ensuing few days, there were numerous discussions and negotiations conducted between Southern Mineral and PetroCorp management as well as their legal and financial advisors. On December 6, 2000, Mr. Christopher transmitted to Mr. Mikel a revised letter of intent providing merger consideration in the amount of $4.71 per Southern Mineral common share payable in cash, PetroCorp common stock or a combination of the two. On December 8, 2000, the Southern Mineral board of directors met to discuss the letter of intent submitted by PetroCorp. Following a presentation on the status of these negotiations by members of management and representatives of Petrie Parkman, the board authorized management to execute the letter of intent, which included, among other things, provisions relating to the exchange of confidential information, and other due diligence matters, and directed the management of Southern Mineral to continue to discuss, analyze and negotiate a possible merger with PetroCorp. During the next two weeks, Southern Mineral personnel and representatives of various consulting firms, including Netherland, Sewell & Associates, Inc., Alan C. Prigge & Associates, Inc., Environmental Compliance Associates, and KPMG LLP, as well as representatives of Akin Gump, and Petrie Parkman, conducted and concluded the due diligence on PetroCorp. On December 14, 2000, various members of Southern Mineral's management and board, plus representatives of its consulting groups and financial advisor, attended an all-day due-diligence meeting in PetroCorp's offices in Tulsa, Oklahoma. At the same time, Southern Mineral's counsel initiated the drafting of an agreement and plan of merger among PetroCorp, PetroCorp Acquisition and Southern Mineral. To assist Southern Mineral in its due diligence, PetroCorp provided Southern Mineral with a statement of its summary financial data, including estimates that for 2001 PetroCorp would have discretionary cash flow of $29.5 million and EBITDX, or earnings before interest, taxes, depreciation, depletion and amortization and exploration expense, of $39.9 million . On December 22, 2000, the Southern Mineral board met with management and representatives of Petrie Parkman to discuss the PetroCorp transaction. Management reported on the results of its due diligence. Southern Mineral management then presented its views of the proposed transaction and recommended that the board accept the agreement to merge with PetroCorp. Southern Mineral's legal counsel, Akin Gump, presented a summary of the terms of the merger agreement and discussed various legal issues with the board. Petrie Parkman presented its financial analyses and delivered to the Southern Mineral board its written opinion that, as of December 22, 2000 and based upon and subject to the matters set forth in such opinion, the merger consideration to be received by the holders of Southern Mineral common stock pursuant to the merger agreement was fair from a financial point of view to the holders of Southern Mineral common stock. Following additional discussion on the merits of the proposed transactions, the Southern Mineral board approved the terms of the merger, merger agreement, voting agreements, affiliate agreements and the transactions contemplated by such agreements, and agreed to recommend the merger to the shareholders of Southern Mineral. Following the approval by Southern Mineral's board and the approval of PetroCorp's board of the merger, Southern Mineral and PetroCorp each executed the agreement and plan of merger and later that day issued a press release publicly announcing that PetroCorp and Southern Mineral had entered into the merger agreement. All of the shareholder agreements were executed concurrent with the merger agreement except for St Paul's shareholder agreement, which was executed on January 5, 2001. In connection with Southern Mineral board's approval of the first amendment to the merger agreement on March 9, 2001, Petrie Parkman confirmed its opinion dated December 22, 2000 by delivery of a written opinion to the Southern Mineral board dated March 9, 2001. The opinion dated March 9, 2001 is attached as Annex VIII to this document and we urge you to read it in its entirety. For a discussion of the amendment to the merger agreement, see "The Merger Agreement -- Amendment No. 1 to Merger Agreement" on page 62. 28 Reasons for the Merger; Recommendations of the Board of Directors PetroCorp Reasons for the Merger The members of PetroCorp's board of directors have unanimously determined that the merger agreement and the merger are fair to and in the best interest of its shareholders. In reaching its decision to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock, the PetroCorp board of directors consulted with PetroCorp's legal advisors and its management, as well as the acquisitions department and other financial and engineering personnel of Kaiser-Francis. The material factors considered by the PetroCorp board of directors included the following: . Increased Financial Strength, Critical Mass and Scope. The merger will give PetroCorp increased size, which could allow it to aggressively compete for and secure future growth opportunities both in the United States and Canada. . Increased Shareholder Liquidity and Diversity. The merger will increase the PetroCorp shareholder base, resulting in greater liquidity for shares and the dilution of ownership interests of significant shareholders. . Expanded Prospect Portfolio. The merger will expand PetroCorp's existing portfolio with several new targets distributed across core areas where both companies have achieved high rates of return. . Enhanced Reserve Base and Growth Potential. The merger will increase PetroCorp's reserves by approximately 75% and expand potential reserve growth. . Increased Cash Flows Stability. The combination of the two producing property portfolios will decrease the reliance on cash flow from any individual well or area, reducing operational risk. . Geographic and Operational Efficiencies. Southern Mineral's properties and prospects complement, and are located in the same core areas as, PetroCorp's, resulting in economic and operational efficiencies. . Leverage of Existing Expertise and Infrastructure. The merger will enable PetroCorp to more fully use its existing technical and operational expertise and in-place infrastructure through its management agreement with Kaiser-Francis, in the United States and in Canada. The PetroCorp management agreement with Kaiser-Francis allows PetroCorp to add Southern Mineral's reserves at a per mcf level of general and administrative expense below Southern Mineral's current levels. . Ability to Grow While Incurring Comparatively Less Debt. By giving merger consideration consisting of part cash and part PetroCorp common stock, PetroCorp is able to acquire substantial oil and gas reserves, on favorable terms at a time of high oil and gas prices, with less debt than would otherwise be required. The potential risks and disadvantages to PetroCorp's shareholders identified by the PetroCorp board of directors as material included the following: . Cost Related to Closing the Merger Transaction. The process of effecting the merger transaction will require the investment of a significant amount of time and resources, including time spent by PetroCorp management away from daily operations and monies paid to legal, accounting and other financial professionals, with closing being subject to various conditions, including shareholder approval. See "The Merger Agreement -- Conditions to Closing" on page 60. PetroCorp will have to pay most of its merger related costs and expenses, even if the merger does not close; . Difficulties Inherent in Combining Companies. The integration of PetroCorp and Southern Mineral operations and systems may involve unforseen difficulties and fail to achieve the cost savings and other benefits anticipated by the parties, while at the same time distracting PetroCorp management from regular business concerns; 29 . Sharing of PetroCorp Assets. As a result of the merger, the benefits of PetroCorp's long-term exploration projects and high-quality reserves, will be shared by stockholders of Southern Mineral, rather than enjoyed solely by PetroCorp's stockholders; and . Increase in Size. The increased size and property portfolio of PetroCorp would result in increased regulation which may in turn distract management from asset development and create additional compliance expense. PetroCorp's increased reserve base will also make it more difficult to find exploration and acquisition opportunities to replace production. Drilling levels required to replace reserves will likely increase PetroCorp's exposure to drilling risk. PetroCorp's increased operation levels will also increase the risk that Kaiser-Francis may fail to perform under its management agreement with PetroCorp. For additional discussion of the risks associated with the merger see "Risk Factors" beginning on page 18. Because of the wide variety of factors considered in connection with its evaluation of the merger, the PetroCorp board of directors did not find it practicable to, and did not, quantify or otherwise attempt to assign relative significance to the specific factors considered in reaching its conclusions. In addition, individual directors may have given different significance to different factors. For the reasons discussed above, the members of the PetroCorp board of directors have determined that the terms of the merger are fair to, and in the best interests of, PetroCorp and the PetroCorp shareholders. Accordingly, the members of the PetroCorp board of directors unanimously recommend that the PetroCorp shareholders vote to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock. Southern Mineral Reasons for the Merger The members of the Southern Mineral board of directors, each of which is an independent director, have unanimously determined that the merger agreement is fair to and in the best interests of Southern Mineral and its shareholders. Accordingly, the board has approved the merger agreement and the transactions contemplated thereby, including the merger and the transactions contemplated by the shareholder agreements. In reaching these decisions, the board consulted with senior management, as well as its legal counsel, independent accountants and financial advisors and considered the following as material factors: . Benefits Created by the Merger. The benefits created by the merger, including the opportunities for costs savings and economies of scale, should result in an improved financial condition and improved results of operations of the combined company. PetroCorp's business platform provides the ready-made operating resources and experience, inventory of properties, and strategic plan for Southern Mineral, which recently restructured its operations. In turn, Southern Mineral provides PetroCorp with additional high-quality properties and related cash flow. . Complementary Assets. Both PetroCorp and Southern Mineral have operations in the Gulf Coast region and own oil and gas properties in Alberta, Canada. The combined company expects to benefit from combining its operations in this core operating area while also benefiting from greater diversity of operations in the Gulf Coast region and the added diversity of properties in Canada. . Premium to Trading Price. The consideration offered under the transaction represented approximately a 49% premium over the average closing price of Southern Mineral's common stock for the 20 trading days preceding the announcement of the merger. . Adequate Capital Resources and Liquidity. After the merger, Southern Mineral anticipates that the combined company will have access to capital resources adequate to pursue a more expansive exploration and development plan. In addition to cash on hand, substantial cash flows from operations and funds available under an existing credit facility, we anticipate that the combined company will be 30 able to access the private and public capital markets with equity and debt offerings on more favorable terms than would have been available to Southern Mineral as a separate company. . Ability to Consider Competing Offers. The merger agreement does not preclude the initiation of competing offers by other potential bidders. If another party delivers an unsolicited offer to Southern Mineral, the Southern Mineral board may consider and accept it if the offer is superior to the merger from a financial point of view and the board determines in good faith that it is required to further investigate such offer to comply with its fiduciary duty imposed by law. If the board accepts a superior offer, Southern Mineral is required to pay PetroCorp a cash termination fee of $2,350,000. As of the date of this document, Southern Mineral has not received any competing offers. . Increased Critical Mass and Scope. The combined company's ability to compete should be substantially enhanced by the merger, which will create a larger, better capitalized, more widely-held company, with greater operational strengths and exploration and development opportunities. . Business Strategy/Hiring and Evaluating Staff. The merger will provide Southern Mineral with immediate access to substantial additional expertise and infrastructure, including experienced personnel and proprietary information. Southern Mineral's recent bankruptcy reorganization required it to divest certain non-core assets and to substantially reduce its technical and administrative staff. In order to realize its growth potential, Southern Mineral would have to expand its strategic plan beyond the bankruptcy reorganization context, and hire and retain substantial additional personnel to implement and execute that plan. After the merger, the combined company will continue to have access to and utilize the staff of Kaiser-Francis under its management agreement with PetroCorp. . Increased Stability of Cash Flows and Growth Potential Through Diversification. Following the transaction, the production value of the combined company's properties will be dispersed among a greater number of properties. This diversification of operations over a greater number of properties is expected to mitigate risks inherent in operating a small number of properties in a concentrated area. The combined company will also have a larger prospect inventory, which is expected to provide the combined company with a greater ability to sustain growth. . Increased Shareholder Liquidity. The PetroCorp common stock to be received by the Southern Mineral shareholders will be listed on the AMEX and may be more widely traded than shares of Southern Mineral common stock, resulting in enhanced liquidity for our shareholders. Listing on the AMEX, as compared to Southern Mineral's current listing on the OTC Bulletin Board, exposes Southern Mineral shareholders to a larger investor population as certain larger institutions limit their investments to companies listed with a national exchange or market. Additionally, if Southern Mineral's shareholders do not elect to receive PetroCorp stock, they will receive cash in exchange for their shares of Southern Mineral stock. In reaching its determination approving the merger for submission to the shareholders, the Southern Mineral board also considered and evaluated information presented by the management of Southern Mineral with respect to the transaction. In this regard, the Southern Mineral board considered information relating to: . the results of operations, financial and operating performance, financial condition and prospects of and the opportunities available to PetroCorp, Southern Mineral and the combined company, and the risks involved in attempting to grow Southern Mineral as an independent company; . the reserves, asset quality and cost structure of PetroCorp and Southern Mineral; . the strategic and financial alternatives available to Southern Mineral; . the results and scope of the due diligence review conducted by Southern Mineral's management with respect to PetroCorp's business, properties, operations and prospects; . historical, recent and potential future trading prices and trading multiples of the common stock of PetroCorp and Southern Mineral; 31 . historical, recent and potential future commodity prices of oil and gas; . the terms of the merger agreement; . the financial analyses and written opinion of Petrie Parkman dated December 22, 2000 with respect to the fairness from a financial point of view, as of December 22, 2000 and based upon and subject to the matters set forth in such opinion, of the merger consideration to the holders of Southern Mineral common stock; and . the advice of outside counsel to Southern Mineral with respect to the fiduciary duties and obligations of the disinterested members of the board in considering the transaction. The potential risks and disadvantages to Southern Mineral's shareholders identified by the Southern Mineral board of directors as material included the following: . Lack of Liquidity of PetroCorp Stock. Southern Mineral shareholders' liquidity may not be enhanced by the merger because PetroCorp's stock has traditionally not been very liquid. For example, during November 2000, the month before the merger agreement was signed, 59,400 Southern Mineral shares were traded while only 2,200 PetroCorp shares were traded, even though PetroCorp's stock, as discussed above, is traded on the AMEX, a national exchange, while Southern Mineral's shares are traded on the OTC Bulletin Board. . Cost Related to Closing the Merger Transaction. The process of effecting the merger transaction will require Southern Mineral management to invest a significant amount of time and resources, meaning they will have less time to devote to daily operations. The merger also involves significant expenses payable to legal, accounting and other financial professionals, with closing being subject to various conditions, including shareholder approval. See "The Merger Agreement--Conditions to Closing" on page 60. Southern Mineral will have to pay many merger related costs and expenses even if the merger does not close; . Difficulties Inherent in Combining Companies. The integration of PetroCorp and Southern Mineral operations and systems may involve unforseen difficulties and fail to achieve the cost savings and other benefits anticipated by the parties, while at the same time distracting PetroCorp management from regular business concerns; . Volatility of PetroCorp stock prices. The exchange ratio will not be adjusted as a result of any decrease or increase in the price of PetroCorp common stock. Therefore, because the market price of PetroCorp common stock is subject to fluctuation, the market price at the time of the merger of the PetroCorp stock to be received by the Southern Mineral shareholders that make valid stock elections may be lower than $10.00 per share, which was the value attributed to the PetroCorp stock at the time we signed the merger agreement, and lower than the market price of PetroCorp common stock on the date of this document, the date of the special meetings, or the date that the stock election period ends. For additional discussion of the risks associated with the merger, including these risk factors, see "Risk Factors" beginning on page 18. The board also considered the option of remaining independent versus the relative merits of the combination with PetroCorp. Based on all of these matters the board unanimously approved the merger and unanimously recommended the merger agreement and the merger for approval to its shareholders. In reaching the determination to approve and recommend the merger agreement and the merger to its shareholders, the Southern Mineral board did not assign any relative or specific weight to the foregoing factors which were considered, and individual directors may have given differing significance to the various factors. 32 Accounting Treatment The merger will be accounted for as a purchase. Under this accounting method, PetroCorp will record Southern Mineral's assets and liabilities at their fair values, and, if the purchase price exceeds the total of these fair values, PetroCorp will record the excess as goodwill. PetroCorp will include the revenues and expenses of Southern Mineral in PetroCorp's financial statements from the date of the consummation of the merger. Regulatory Approvals No filing under the Hart-Scott-Rodino Antitrust Improvement Act of 1976 was required in connection with the merger. Neither Southern Mineral nor PetroCorp is aware of a material governmental or regulatory approval required for completion of the merger, other than compliance with the applicable corporate laws of Texas and Nevada. U.S. Federal Income Tax Consequences of the Merger The following discussion summarizes the anticipated material U.S. federal income tax consequences of the merger to Southern Mineral shareholders. Akin, Gump, Strauss, Hauer & Feld, L.L.P. has acted as counsel to Southern Mineral and this discussion constitutes its legal opinion as to the matters discussed herein. This discussion addresses only those shareholders who hold their shares of Southern Mineral common stock as a capital asset, and does not address all of the U.S. federal income tax consequences that may be relevant to particular Southern Mineral shareholders in light of their individual circumstances, or to Southern Mineral shareholders that are subject to rules, such as: . financial institutions; . mutual funds; . tax-exempt organizations; . insurance companies; . dealers in securities or foreign currencies; . traders in securities who elect to apply a mark-to-market method of accounting; . foreign holders; . persons who hold shares of Southern Mineral common stock as a hedge against currency risk or as part of a straddle, constructive sale or conversion transaction; or . holders who acquired their shares of Southern Mineral common stock upon the exercise of warrants or employee stock options or otherwise as compensation. The following discussion is not binding on the Internal Revenue Service. It is based upon the Internal Revenue Code of 1986, as amended, and the regulations, rulings and decisions thereunder in effect as of the date of this document, all of which are subject to change, possibly with retroactive effect. Tax consequences under state, local and foreign laws and U.S. federal laws other than U.S. federal income tax laws, are not addressed. Southern Mineral shareholders are urged to consult their tax advisors as to the specific tax consequences to them of the merger, including the applicability and effect of U.S. federal, state and local and foreign income and other tax laws in their particular circumstances. If the merger qualifies as a reorganization within the meaning of Section 368(a) of the Internal Revenue Code, holders of shares of Southern Mineral common stock that receive shares of PetroCorp common stock in the merger will not recognize gain or loss for U.S. federal income tax purposes, except with respect to cash they receive as part of the merger consideration. Each shareholder's aggregate tax basis in the shares of PetroCorp common stock received in the merger would be the same as such shareholder's aggregate tax basis 33 in the shares of Southern Mineral common stock surrendered in the merger increased by any gain recognized and, decreased by any cash received and the amount of any tax basis allocable to any fractional share interest for which cash is received. The holding period of the shares of PetroCorp common stock received in the merger by a holder of shares of Southern Mineral common stock would include the holding period of shares of Southern Mineral common stock that such shareholder surrendered in the merger. A holder of shares of Southern Mineral common stock that receives cash in lieu of a fractional share of PetroCorp common stock would recognize gain or loss equal to the difference between the amount of cash received and such shareholder's tax basis in the shares of Southern Mineral common stock allocable to the fractional share. That gain or loss generally would constitute capital gain or loss. In the case of an individual shareholder, any of this capital gain generally would be subject to a maximum U.S. federal income tax rate of 20% if the individual has held his shares of Southern Mineral common stock for more than 12 months on the date of the merger. The deductibility of capital losses is subject to limitations for both individuals and corporations. If, however, the merger does not qualify as a tax free reorganization, a Southern Mineral shareholder would recognize gain (or loss) equal to the amount by which the cash and fair market value of the PetroCorp shares received in exchange for his Southern Mineral shares pursuant to the merger exceeds (or is less than) her basis in her Southern Mineral shares surrendered or cancelled in the merger. Assuming the Southern Mineral shareholder held her shares as a capital asset, any such gain or loss would be capital gain or loss for federal income tax purposes, and, if her holding period were at least 12 months, long term capital gain. Long term capital gain is generally taxed at a maximum rate of twenty percent (20%). A Southern Mineral shareholder's basis in his shares would be equal to their fair market value on the date of the exchange and his holding period would begin on the date of exchange. Because shares of PetroCorp common stock will remain unchanged in the merger, the merger will not cause PetroCorp shareholders to recognize any gain or loss. No gain or loss will be recognized by PetroCorp, Southern Mineral or PetroCorp Acquisition. Dissenters' Rights Under Nevada law, Southern Mineral shareholders may be entitled to dissenters' rights in the merger. Under our merger structure, the availability of dissenters' rights for Southern Mineral shareholders depends on the OTC Bulletin Board, on which the Southern Mineral stock is listed, being a "national securities exchange," as contemplated by the Nevada statutes. Currently, Nevada law is unsettled on this point. The following information is presented in case it is determined that Southern Mineral's shareholders have dissenters' rights in connection with the merger. A copy of the applicable Nevada statutes regarding dissenters' rights are attached to this document as Annex IX. Southern Mineral shareholders who are considering exercising dissenters' rights, to the extent that they apply to the merger, should review the statute carefully, particularly the steps required to perfect dissenters' rights. Set forth below is a summary of the steps to be taken by a holder of record to exercise the right to dissent. This summary should be read in conjunction with the full text of the attached statute. To exercise a right to dissent: . before the vote is taken, you must deliver written notice to the Southern Mineral secretary stating that you intend to demand payment for your shares if the merger is completed; and . you must NOT vote your shares in favor of the merger either by proxy or in person. If you send written notice of your intent to dissent before the vote on the merger, Southern Mineral must send you a written dissenters' notice within 10 days after the merger is effective telling you: . where your demand for payment must be sent and where and when your stock certificates must be deposited; . what happens if you own shares but do not have the stock certificate; and 34 . the date by which Southern Mineral must receive the demand form, which must be between 30 and 60 days after notice delivery, and providing you: . a form to demand payment; and . a copy of the statute. Your failure to demand payment in the proper form or deposit your certificates as described in the dissenters' notice will terminate your right to receive payment for your Southern Mineral shares. Your rights as a Southern Mineral shareholder will continue until those rights are cancelled or modified by the completion of the merger. If you acquired your shares before the merger was made public, within 30 days of receipt of a properly executed demand for payment, Southern Mineral must pay you what it determines to be the fair market value plus interest for your shares. Payment must be accompanied by specific financial records of Southern Mineral, a statement of Southern Mineral's fair value estimate, including how interest was calculated, information regarding your right to challenge the fair value estimate, and copies of relevant portions of the Nevada Revised Statutes. If you acquired your shares after the merger was first made public, you are only entitled to receive payment of the amount Southern Mineral estimates is the fair value of your shares if you accept that estimate. If you wish to contest that estimate, you may do so, but you will receive no payment until the contest is resolved. Within 30 days from the receipt of the fair value payment or notice, you may notify Southern Mineral in writing of your own fair value estimate and demand payment of the amount not yet paid. Failure to demand payment within 30 days of receipt of payment or notice terminates your right to challenge Southern Mineral's calculation of fair value. If you and Southern Mineral cannot agree on fair market value within 60 days after Southern Mineral receives a shareholder demand, Southern Mineral must commence legal action seeking court determination of fair market value. If Southern Mineral fails to commence a legal action within the 60 day period, it must pay each dissenter whose demand remains unsettled the amount they demanded. Proceedings instituted by Southern Mineral will be in Washoe County, Nevada. Costs of legal action will be assessed against Southern Mineral, unless the court finds that the dissenters' acted arbitrarily, vexatiously or not in good faith, in which case costs will be equitably distributed. Attorneys' and expert fees may be awarded in such amount as the court deems equitable against any party the court determines has acted wrongfully. Opinion of Southern Mineral's Financial Advisor Southern Mineral engaged Petrie Parkman & Co., Inc. as its financial advisor on August 18, 2000 in connection with a possible transaction involving Southern Mineral. On December 22, 2000, Petrie Parkman delivered to the Southern Mineral board of directors its written opinion that, as of that date and based upon and subject to the matters set forth in such opinion, the merger consideration described in the merger agreement to be received by the holders of Southern Mineral common stock was fair from a financial point of view to the holders of Southern Mineral common stock. In connection with Southern Mineral board's approval of the first amendment to the merger agreement, Petrie Parkman confirmed its opinion by delivery of a written opinion to the Southern Mineral board of directors dated March 9, 2001. Pursuant to an engagement letter between Petrie Parkman and Southern Mineral dated August 18, 2000, Southern Mineral agreed to pay to Petrie Parkman a transaction fee based on the transaction value and conditioned upon closing of a merger. Assuming the merger is consummated at the merger consideration described in the merger agreement, Southern Mineral and Petrie Parkman estimate that Petrie Parkman's transaction fee will be equal to approximately $1,140,000. In addition, Southern Mineral also agreed to reimburse Petrie Parkman for its reasonable out-of-pocket expenses related to its rendering of financial advisory and investment banking services to Southern Mineral, including the fees and expenses of its legal counsel. 35 Southern Mineral also agreed to indemnify Petrie Parkman and its affiliates, the respective directors, officers, partners, agents and employees of Petrie Parkman and its affiliates, and controlling persons for certain losses, claims, damages, liabilities and expenses related to or arising out of its engagement as financial advisor. The full text of Petrie Parkman's opinion dated March 9, 2001, which contains a description of the assumptions made and matters considered by Petrie Parkman in rendering its opinion, is attached as Annex VIII. Southern Mineral shareholders are encouraged to, and should, read the Petrie Parkman opinion carefully in its entirety. Petrie Parkman's opinions were provided to the Southern Mineral board for its use and benefit and address only the fairness from a financial point of view of the merger consideration to the holders of Southern Mineral common stock. Petrie Parkman's opinions do not address the merits of the underlying decision by Southern Mineral to engage in the merger and do not constitute a recommendation to any shareholder as to how that shareholder should vote at the special meeting. The amount and form of consideration to be paid in the transaction was the result of arms-length negotiations between PetroCorp and Southern Mineral. Petrie Parkman's opinion dated December 22, 2000 and its presentation to the Southern Mineral board on December 22, 2000, and Petrie Parkman's opinion dated March 9, 2001 confirming its opinion dated December 22, 2000, were among many factors taken into consideration by the Southern Mineral board in making its determination to approve and recommend the transaction described in the merger agreement and to approve the first amendment to the merger agreement, respectively. In arriving at its opinion dated March 9, 2001, Petrie Parkman, among other things: 1. reviewed certain publicly available business and financial information relating to PetroCorp and Southern Mineral, including . Annual Reports on Form 10-K and related audited financial statements for the fiscal years ended December 31, 1998 and December 31, 1999, and . Quarterly Reports on Form 10-Q and related unaudited financial statements for the fiscal quarters ended March 31, 2000, June 30, 2000 and September 30, 2000; 2. reviewed a draft dated March 6, 2001, of the Annual Report on Form 10-K for the fiscal year ended December 31, 2000 of Southern Mineral and a draft dated March 6, 2001 of the Annual Report on Form 10-K for the fiscal year ended December 31, 2000 of PetroCorp; 3. reviewed certain estimates of Southern Mineral's reserves, including . estimates of proved and probable oil and gas reserves prepared by Netherland, Sewell & Associates, Inc. (as to United States and Ecuador reserves only) as of December 31, 2000, and . estimates of proved and probable oil and gas reserves prepared by Chapman Petroleum Engineering Ltd. (as to Canadian reserves only) as of December 31, 2000; 4. reviewed certain estimates of PetroCorp's reserves, including . estimates of proved and probable oil and gas reserves prepared by Huddleston & Co., Inc. as of December 31, 2000; 5. analyzed certain historical and projected financial and operating data of . PetroCorp prepared by the management and staff of PetroCorp, and . Southern Mineral prepared in conjunction with, and approved by, the management and staff of Southern Mineral; 6. discussed the current and projected operations and prospects of PetroCorp and Southern Mineral with the management and staff of PetroCorp and Southern Mineral, respectively; 36 7. reviewed the trading history of PetroCorp common stock and Southern Mineral common stock; 8. compared recent stock market capitalization indicators for PetroCorp and Southern Mineral with recent stock market capitalization indicators for certain other publicly-traded independent energy companies; 9. compared the financial terms of the merger with the financial terms of certain other transactions that Petrie Parkman deemed to be relevant; 10. participated in certain discussions and negotiations among the representatives of Southern Mineral, PetroCorp and their financial and legal advisors; 11. reviewed the merger agreement; 12. reviewed a draft dated March 7, 2001 of the first amendment to the merger agreement; and 13. reviewed such other financial studies and analyses and performed such other investigations and took into account such other matters as Petrie Parkman had deemed necessary or appropriate. In preparing its opinions, Petrie Parkman assumed and relied upon, without assuming any responsibility for or independently verifying, the accuracy and completeness of any information supplied or otherwise made available to it. Petrie Parkman further relied upon the assurances of the management of Southern Mineral and PetroCorp that they were unaware of any facts that would make the information provided to Petrie Parkman incomplete or misleading in any material respect. With respect to projected financial and operating data, Petrie Parkman assumed that the data had been reasonably prepared on bases reflecting the best currently available estimates and judgments of the management and staff of Southern Mineral and PetroCorp, respectively, relating to the future financial and operational performance of each company. With respect to the estimates of oil and gas reserves, Petrie Parkman assumed that they had been reasonably prepared on bases reflecting the best available estimates and judgments of the management and staff of Southern Mineral or PetroCorp or their respective engineering consultants relating to the oil and gas properties of Southern Mineral and PetroCorp, respectively. Petrie Parkman did not make an independent evaluation or appraisal of the assets or liabilities of Southern Mineral or PetroCorp nor, except for the estimates of oil and gas reserves referred to above, was Petrie Parkman furnished with such an evaluation or appraisal. In addition, Petrie Parkman did not assume any obligation to conduct, and did not conduct, any physical inspection of the properties or facilities of Southern Mineral or PetroCorp. In developing its opinions, Petrie Parkman relied upon Southern Mineral as to certain legal, tax, and accounting aspects of the transaction described in the merger agreement. Petrie Parkman assumed, based on discussions with the management and staff of Southern Mineral, that no adjustments to the merger consideration will be required under the merger agreement on the basis of the transaction costs incurred by Southern Mineral. For purposes of the March 9, 2001 opinion, Petrie Parkman also assumed that the first amendment to the merger agreement executed and delivered by the parties was substantially similar to the draft of the first amendment to the merger agreement reviewed by Petrie Parkman. Petrie Parkman further assumed that the merger will be consummated on the terms and conditions contemplated in the merger agreement. Petrie Parkman was not asked to consider, and its opinions do not address, the after-tax consequences of the merger to any particular shareholder of Southern Mineral or the price at which PetroCorp common stock will actually trade following the announcement or consummation of the merger. 37 Petrie Parkman's opinions were rendered on the basis of conditions in the securities markets and the oil and gas markets prevailing as of the respective dates of its opinions and the condition and prospects, financial and otherwise, of PetroCorp and Southern Mineral as they had been represented to Petrie Parkman as of the respective dates of its opinions or as they were reflected in the materials and discussions described above. The following is a summary of the financial analyses performed by Petrie Parkman in connection with the preparation of the Petrie Parkman opinion dated December 22, 2000 and presented to the Southern Mineral board of directors on December 22, 2000. Petrie Parkman reviewed and updated such analyses in connection with its preparation of the opinion dated March 9, 2001. This summary includes information presented in tabular format. In order to fully understand these financial analyses, the tables must be read together with the text accompanying each summary. The tables alone do not constitute a complete description of these financial analyses. Considering the data set forth in the tables without considering the full narrative description of these analyses, including the methodologies and assumptions underlying these analyses, could create a misleading or incomplete view of these financial analyses performed by Petrie Parkman. Historical Stock Trading Ratio Analysis. Petrie Parkman analyzed the historical ratios of the closing prices of Southern Mineral common stock divided by corresponding closing prices of PetroCorp common stock for the period from August 4, 2000, the first full day of trading after the announcement by Southern Mineral that the order confirming its plan of reorganization became effective, to December 19, 2000. The average stock trading ratio for the period from August 4, 2000 to December 19, 2000 was 0.353 as compared to the exchange ratio of .471 shares of common stock of PetroCorp per share of common stock of Southern Mineral, unadjusted for transaction costs, applicable to the stock portion of the merger consideration. Discounted Cash Flow Analysis - Southern Mineral. Petrie Parkman conducted a discounted cash flow analysis for the purpose of determining the equity reference value range per share of Southern Mineral common stock. Petrie Parkman calculated the net present value of after-tax cash flows of Southern Mineral's oil and gas reserve assets based on the proved and probable reserve estimates referred to above and for its non-reserve assets utilizing information provided by Southern Mineral. Petrie Parkman evaluated five scenarios in which the principal variables were oil and gas prices. The five pricing scenarios, which were referred to by Petrie Parkman as "Pricing Case I", "Pricing Case II", "Pricing Case III", the "Strip Pricing Escalated Case", and the "Strip Pricing Flat Case" were based on benchmarks for spot sales of West Texas Intermediate crude oil and for spot sales of Henry Hub gas. The Strip Pricing Escalated Case and the Strip Pricing Flat Case were based upon the average of oil and gas futures contract prices quoted on the New York Mercantile Exchange. Petrie Parkman applied appropriate quality and transportation adjustments to these benchmarks. Year 2000 oil prices utilized in the analysis for Pricing Cases I, II, III, Strip Pricing Escalated and Strip Pricing Flat were based on the blended average of actual oil prices from October 1, 2000 through December 19, 2000 and benchmark scenarios for the remainder of 2000. Projected benchmark prices for Pricing Cases I, II and III of $19.00, $21.00 and $23.00 per barrel, respectively, were escalated at the rate of 3% per year starting in 2001. The Strip Pricing Escalated Case assumed benchmark oil prices of $26.30, $23.20, $22.01, $21.22 and $20.92 for the years 2001, 2002, 2003, 2004 and 2005, respectively, and was escalated annually following the year 2005 at the rate of 3%. Benchmark oil prices for the Strip Pricing Flat Case were projected to be the same as the Strip Pricing Escalated Case through 2005, with prices held constant thereafter. Year 2000 gas prices utilized in the analysis for Pricing Cases I, II, III, Strip Pricing Escalated and Strip Pricing Flat were based on the blended average of actual gas prices from October 1, 2000 through December 19, 2000 and benchmark scenarios for the remainder of 2000. Projected benchmark prices for Pricing Cases I, II and III of $2.50, $3.00 and $3.50 per million British thermal units, respectively, were escalated at the rate of 3% per year starting in 2001. The Strip Pricing Escalated Case assumed benchmark gas prices of $6.07, $4.37 and $3.86 for the years 2001, 2002 and 2003 respectively, and was escalated annually 38 following the year 2003 at the rate of 3%. Benchmark gas prices for the Strip Pricing Flat Case were projected to be the same as the Strip Pricing Escalated Case through 2003, with prices held constant thereafter. Operating and capital costs were escalated at 3% per year starting in year 2001. Applying various after-tax discount rates ranging from 10.0% to 40.0% depending on reserve category to the after-tax cash flows, assuming a carry- over of Southern Mineral's existing tax position as of December 31, 1999 and deducting long term debt of $19.7 million and adding net working capital of $0.2 million, the discounted cash flow analysis indicated the following equity reference value ranges per fully-diluted share of Southern Mineral common stock as compared to the merger consideration, unadjusted for transaction costs, valued at $4.71 per share. Pricing Case Pricing Case I II Pricing Case III Strip Pricing Esc. Strip Pricing Flat ------------- ------------- ---------------- ------------------ ------------------ Equity Reference Value Range per Common Share................. $2.78 - $3.29 $3.60 - $4.23 $4.44 - $5.18 $4.87 - $5.59 $4.57 - $5.18 Property Transactions Analysis - Southern Mineral. Petrie Parkman reviewed selected publicly available information for 78 announced oil and gas property transactions and proprietary information for two oil and gas property acquisition transactions between January 1997 and December 2000 in the Gulf Coast region of the United States and in Canada. Petrie Parkman focused on transactions involving assets and properties which it determined to be most comparable to assets and properties of Southern Mineral based on certain attributes of each transaction, such as size of the transaction, mix of gas and oil reserves, location of the assets, operational profile of the assets and other known characteristics. Petrie Parkman calculated the purchase price of reserves per unit of equivalent reserves for the acquired assets in each transaction. For purposes of this analysis, equivalency is used to compare quantities of oil with quantities of gas using a one barrel of oil to six thousand cubic feet of gas conversion ratio, or Mcfe6. Based on a review of the purchase price of reserves per unit of equivalent reserves, Petrie Parkman determined benchmark ranges of purchase prices to Southern Mineral's corresponding proved reserve figures in order to yield enterprise reference value ranges for Southern Mineral's proved reserves. The number of transactions per region and the maximum, mean and minimum purchase prices for these transactions are set forth in the following table. Gulf Coast Canada ----- ------ Number of Transactions......... 47 33 Purchase Price of Reserves / Proved Reserves ($/Mcfe6) Maximum.................... $1.63 $1.29 Mean....................... $0.86 $0.81 Minimum.................... $0.20 $0.52 Petrie Parkman selected benchmark ranges of purchase price per unit of equivalent reserves of $0.81 to $1.00 for Southern Mineral's proved U.S. assets and $0.80 to $0.90 for Southern Mineral's proved Canadian assets. Petrie Parkman applied the benchmark ranges of purchase price per unit to Southern Mineral's proved reserve figures and, after adjusting for Southern Mineral's non-reserve assets, determined an enterprise reference value range. Petrie Parkman then deducted long-term debt of $19.7 million and added net working capital of $0.2 million to such enterprise reference value range and divided the resulting figure by the fully-diluted number of shares of Southern Mineral common stock outstanding to arrive at an equity reference value range per fully-diluted share of Southern Mineral common stock of $2.95 to $3.90 as compared to the merger consideration, unadjusted for transaction costs, valued at $4.71 per share. Company Transaction Analysis - Southern Mineral. Petrie Parkman reviewed selected publicly available information on the following 18 company acquisition transactions and offers for control involving companies in the oil and gas exploration and production industry that were announced between January 1997 and December 39 2000. Petrie Parkman focused on certain transactions because of the similarities between Southern Mineral and the target companies in such transactions, such as the company's size, size of reserve base, mix of gas and oil reserves and other characteristics of the targets' reserves, capitalization and other identifiable characteristics.

American Exploration Company 6/24/97 Forcenergy Inc Convest Energy Corporation 6/20/97 Using publicly available information, Petrie Parkman calculated purchase price equity multiples of estimated current year discretionary cash flow and total investment, which Petrie Parkman defined for the purposes of this analysis as purchase price of equity plus net obligations assumed, multiples of estimated current year earnings before interest, taxes, depreciation, depletion and amortization and exploration expense, or EBITDX, for the target company in each transaction. Petrie Parkman also calculated the implied purchase price of reserves, which Petrie Parkman defined for the purposes of this analysis as total investment less undeveloped acreage value and other assets at book value, multiples of equivalent proved reserves for the target company in each transaction and multiples of standardized measure of future net cash flows (referred to as "Standardized Value") for the target company in each transaction. The minimum, median, mean, and maximum implied multiples in these transactions are set forth below. The table also includes benchmark multiple ranges selected by Petrie Parkman based on a review of the implied multiples in the recent transactions. Implied Multiples in Recent Transactions ---------------------------- Benchmark Minimum Median Mean Maximum Range ------- ------ ----- ------- ------------- Purchase Price / Current Year's Estimated Discretionary Cash Flow............................... 3.7x 5.7x 5.4x 9.2x 2.0x - 3.0x Total Investment / Current Year's Estimated EBITDX................... 2.4x 5.7x 6.2x 10.8x 3.0x - 4.0x Implied Purchase Price of Reserves / Equivalent Proved Reserves ($/Mcfe6)................. $0.57 $1.10 $1.20 $2.25 $1.00 - $1.25 Implied Purchase Price of Reserves / Standardized Value...... 0.6x 1.2x 1.3x 2.4x 0.9x - 1.1x Petrie Parkman applied the benchmark multiples to Southern Mineral's current year estimated discretionary cash flow and EBITDX, equivalent proved reserves, and Standardized Value to determine enterprise reference value ranges. 40 Petrie Parkman also performed a premium analysis for the same universe of company acquisition transactions and offers for control, which compared the offer price per target company share with the target company's share price measured one day and 30 days prior to the public announcement of the offer. The maximum, mean, median and minimum premiums (which Petrie Parkman defined for the purposes of this analysis as excess of offer price over target company's stock price stated as a percentage above the target company's stock price), together with benchmark premium ranges selected by Petrie Parkman based on a review of the implied premiums, for these periods were as follows: Implied Premiums in Recent Transactions ---------------------------- Benchmark Minimum Median Mean Maximum Range ------- ------ ---- ------- --------- One Day Prior............................ -9.8% 8.3% 11.5% 66.9% 17% - 21% 30 Days Prior............................ -5.3% 11.5% 20.1% 74.7% 20% - 25% Petrie Parkman applied the range of benchmark premiums to the corresponding prices of Southern Mineral common stock at one day and 30 days prior to the public announcements of the offer to determine enterprise reference value ranges. After selecting a composite enterprise reference value range and deducting long-term debt of $19.7 million, adding net working capital of $0.2 million and dividing by the fully-diluted number of shares of Southern Mineral common stock outstanding, the resulting equity reference value range per fully-diluted share was $3.98 to $5.17 as compared to the merger consideration, unadjusted for transaction costs, valued at $4.71 per share. Capital Market Comparison - Southern Mineral. Using publicly available information, Petrie Parkman calculated market capitalization multiples of estimated current year's and estimated 2001 discretionary cash flow for six publicly traded companies. Petrie Parkman also calculated enterprise value multiples of estimated current year's and estimated 2001 EBITDX, proved reserves, and Standardized Value for those companies. In each case, multiples of estimated discretionary cash flow and EBITDX were based upon published equity research analyst estimates. Petrie Parkman defined market capitalization for purposes of this analysis as the market value of common equity as of December 19, 2000. Petrie Parkman determined the enterprise value of each company by adding the sum of its long-term and short-term debt to the sum of the market value of its common equity, the market value of its preferred stock (or, if not publicly traded, liquidation or book value) and the book value of its minority interest in other companies and subtracting net working capital. Based upon Petrie Parkman's view of the comparability of operating and financial characteristics (such as size of reserve base, mix of gas and oil reserves, reserve life, market value of equity, enterprise value and capitalization), Petrie Parkman selected the following companies for this analysis: . 3TEC Energy Corporation . Bellwether Exploration Company . Clayton Williams Energy, Inc. . Hallwood Energy Corporation . Key Production Company, Inc. . Remington Oil & Gas Corporation The minimum, median, mean and maximum multiples for the six companies are set forth below. The table also includes benchmark multiple ranges selected by Petrie Parkman based on a review of the comparable company multiples. Comparable Company Multiples --------------------------- Benchmark Measure Minimum Median Mean Maximum Range - ------- ------- ------ ---- ------- ----------- Market Capitalization / 2000 Estimated Discretionary Cash Flow...... 1.5x 3.2x 3.1x 4.6x 2.0x - 3.0x Market Capitalization / 2001 Estimated Discretionary Cash Flow...... 1.3x 2.9x 2.8x 4.4x 1.5x - 2.5x 41 Comparable Company Multiples ---------------------------- Benchmark Measure Minimum Median Mean Maximum Range - ------- ------- ------ ----- ------- ------------- Enterprise Value / 2000 Estimated EBITDX.................. 3.5x 4.1x 4.1x 4.7x 3.5x - 4.0x Enterprise Value / 2001 Estimated EBITDX.................. 2.8x 3.5x 3.8x 5.2x 3.0x - 3.5x Enterprise Value / Proved Reserves ($/Mcfe6)......................... $0.84 $1.76 $1.76 $2.84 $1.00 - $1.20 Enterprise Value / Standardized Value............................. 0.9x 1.5x 1.6x 2.6x 1.0x - 1.1x From the enterprise reference value ranges implied by applying the benchmark multiples to Southern Mineral's estimated current year and 2001 estimated discretionary cash flow, estimated current year and 2001 estimated EBITDX, proved reserves and Standardized Value, Petrie Parkman determined a composite enterprise reference value range. After deducting long term debt of $19.7 million and adding net working capital of $0.2 million to the composite enterprise reference value range and dividing by the fully-diluted number of shares of Southern Mineral common stock outstanding, the equity reference value range per fully-diluted share of Southern Mineral common stock was $3.98 to $4.77 as compared to the merger consideration, unadjusted for transaction costs, valued at $4.71 per share. Discounted Cash Flow Analysis - PetroCorp. Petrie Parkman conducted a discounted cash flow analysis for the purpose of determining the equity reference value range per share of PetroCorp common stock. Petrie Parkman calculated the net present value of after-tax cash flows of PetroCorp's oil and gas reserve assets based on the proved and probable reserve estimates referred to above and for its non-reserve assets utilizing information provided by PetroCorp. Petrie Parkman evaluated the same five pricing scenarios and used the same operating and capital cost escalation assumptions that were used in the Southern Mineral Discounted Cash Flow Analysis. Applying various after-tax discount rates ranging from 10.0% to 40.0% depending on reserve category to the after-tax cash flows, assuming a carry- over of PetroCorp's existing tax position as of December 31, 1999 and deducting long term debt of $34.4 million and adding net working capital of $6.2 million, the discounted cash flow analysis indicated the following equity reference value ranges per share of PetroCorp common stock, on a fully-diluted basis. Pricing Case Pricing Case I Pricing Case II III Strip Pricing Esc. Strip Pricing Flat -------------- --------------- --------------- ------------------ ------------------ Equity Reference Value Range per Common Share................ $6.37 - $7.21 $8.21 - $9.28 $10.05 - $11.34 $11.45 - $12.72 $10.68 - $11.71 Property Transactions Analysis - PetroCorp. Petrie Parkman reviewed selected publicly available information for 155 announced oil and gas property transactions and proprietary information for six oil and gas property acquisition transactions between January 1997 and December 2000 in the Mid- Continent, Gulf Coast, and Rocky Mountain regions of the United States, and in Canada. Petrie Parkman focused on transactions involving assets and properties which it determined to be most comparable to assets and properties of PetroCorp based on certain attributes of each transaction, such as size of the transaction, mix of gas and oil reserves, location of the assets, operational profile of the assets and other known characteristics. Petrie Parkman calculated the purchase price of reserves per unit of equivalent reserves for the acquired assets in each transaction. Based on a review of the purchase price of reserves per unit of equivalent reserves, Petrie Parkman determined benchmark ranges of purchase prices to PetroCorp's corresponding proved reserve figures in order to yield enterprise reference value ranges for PetroCorp's proved reserves. The number of transactions per 42 region and the maximum, mean and minimum purchase prices for these transactions are set forth in the following table. Mid Gulf Rocky Continent Coast Mountain Canada --------- ----- -------- ------ Number of Transactions......... 36 47 45 33 Purchase Price of Reserves / Proved Reserves ($/Mcfe6) Maximum........... $1.42 $1.63 $1.39 $1.29 Mean.............. $0.77 $0.86 $0.75 $0.81 Minimum........... $0.21 $0.20 $0.30 $0.52 Petrie Parkman selected benchmark ranges of purchase price per unit of equivalent reserves of $0.90 to $1.10 for PetroCorp's proved U.S. assets and $0.85 to $1.15 for PetroCorp's proved Canadian assets. Petrie Parkman applied the benchmark ranges of purchase price per unit to PetroCorp's proved reserve figures and, after adjusting for PetroCorp's non-reserve assets, determined an enterprise reference value range. Petrie Parkman then deducted long-term debt of $34.4 million and added net working capital of $6.2 million to such enterprise reference value range and divided the resulting figure by the fully- diluted number of shares of PetroCorp common stock outstanding to arrive at an equity reference value range per fully-diluted share of PetroCorp common stock of $7.67 to $10.53. Company Transaction Analysis - PetroCorp. Petrie Parkman reviewed selected publicly available information on the same 18 company acquisition transactions and offers for control that were reviewed in the Southern Mineral Company Transaction Analysis. Petrie Parkman focused on certain transactions because of the similarities between PetroCorp and the target companies in such transactions, such as the target company's size, size of reserve base, mix of gas and oil reserves and other characteristics of the targets' reserves, capitalization and other identifiable characteristics. Using publicly available information, Petrie Parkman calculated purchase price of equity multiples of estimated current year discretionary cash flow and total investment, which Petrie Parkman defined for the purposes of this analysis as purchase price of equity plus net obligations assumed, multiples of estimated current year earnings before interest, taxes, depreciation, depletion and amortization and exploration expense, or EBITDX, for the target company in each transaction. Petrie Parkman also calculated the implied purchase price of reserves, which Petrie Parkman defined for the purposes of this analysis as total investment less undeveloped acreage value and other assets at book value, multiples of equivalent proved reserves for the target company in each transaction and multiples of standardized measure of future net cash flows (referred to as "Standardized Value") for the target company in each transaction. The minimum, median, mean and maximum implied multiples in these transactions are set forth below. The table also includes benchmark multiple ranges selected by Petrie Parkman based on a review of the implied multiples in the recent transactions. Implied Multiples in Recent Transactions ---------------------------- Benchmark Minimum Median Mean Maximum Range ------- ------ ----- ------- ------------- Purchase Price / Current Year's Estimated Discretionary Cash Flow.............................. 3.7x 5.7x 5.4x 9.2x 2.5x - 3.5x Total Investment / Current Year's Estimated EBITDX.................. 2.4x 5.7x 6.2x 10.8x 3.5x - 4.5x Implied Purchase Price of Reserves / Equivalent Proved Reserves ($/Mcfe6) ........ $0.57 $1.10 $1.20 $2.25 $1.00 - $1.35 Implied Purchase Price of Reserves / Standardized Value.............. 0.6x 1.2x 1.3x 2.4x 0.9x - 1.1x 43 Petrie Parkman applied the benchmark multiples to PetroCorp's current year estimated discretionary cash flow and EBITDX, equivalent proved reserves, and Standardized Value to determine enterprise reference value ranges. Petrie Parkman also performed a premium analysis for the same universe of company acquisition transactions and offers for control, which compared the offer price per target company share with the target company's share price measured one day and 30 days prior to the public announcement of the offer. The minimum, median, mean and maximum premiums (which Petrie Parkman defined for the purposes of this analysis as excess of offer price over target company's stock price stated as a percentage above the target company's stock price), together with benchmark premium ranges selected by Petrie Parkman based on a review of the implied premiums, for these periods were as follows: Implied Premiums in Recent Transactions ---------------------------- Benchmark Minimum Median Mean Maximum Range ------- ------ ---- ------- --------- One Day Prior............................ -9.8% 8.3% 11.5% 66.9% 17% - 21% 30 Days Prior............................ -5.3% 11.5% 20.1% 74.7% 20% - 25% Petrie Parkman applied the range of benchmark premiums to the corresponding prices of PetroCorp common stock to determine enterprise reference value ranges. After selecting a composite enterprise reference value range and deducting long-term debt of $34.4 million, adding net working capital of $6.2 million and dividing by the fully-diluted number of shares of PetroCorp common stock outstanding, the resulting equity reference value range per fully-diluted common share was $9.80 to $11.49. Capital Market Comparison - PetroCorp. Using publicly available information, Petrie Parkman calculated market capitalization multiples of estimated current year's and estimated 2001 discretionary cash flow for six publicly traded companies. Petrie Parkman also calculated enterprise value multiples of estimated current year's and estimated 2001 EBITDX, proved reserves, and Standardized Value for those companies. In each case, multiples of estimated discretionary cash flow and EBITDX were based upon published equity research analyst estimates. Petrie Parkman defined market capitalization for purposes of this analysis as the market value of common equity as of December 19, 2000. Petrie Parkman determined the enterprise value of each company by adding the sum of its long-term and short-term debt to the sum of the market value of its common equity, the market value of its preferred stock (or, if not publicly traded, liquidation or book value) and the book value of its minority interest in other companies and subtracting net working capital. Based upon Petrie Parkman's view of the comparability of operating and financial characteristics (such as size of reserve base, mix of gas and oil reserves, reserve life, market value of equity, enterprise value and capitalization), Petrie Parkman selected the following companies for this analysis: . 3TEC Energy Corporation . Bellwether Exploration Company . Clayton Williams Energy, Inc. . Hallwood Energy Corporation . Key Production Company, Inc. . Remington Oil & Gas Corporation 44 The minimum, median, mean and maximum multiples for the six companies are set forth below. The table also includes benchmark multiple ranges selected by Petrie Parkman based on a review of the comparable company multiples. Comparable Company Multiples ---------------------------- Benchmark Measure Minimum Median Mean Maximum Range - ------- ------- ------ ----- ------- ------------- Market Capitalization / 2000 Estimated Discretionary Cash Flow.......................... 1.5x 3.2x 3.1x 4.6x 3.5x - 4.0x Market Capitalization / 2001 Estimated Discretionary Cash Flow.......................... 1.3x 2.9x 2.8x 4.4x 3.0x - 4.0x Enterprise Value / 2000 Estimated EBITDX............................. 3.5x 4.1x 4.1x 4.7x 3.5x - 4.0x Enterprise Value / 2001 Estimated EBITDX ............................ 2.8x 3.5x 3.8x 5.2x 3.0x - 4.0x Enterprise Value / Proved Reserves ($/Mcfe6) ......................... $0.84 $1.76 $1.76 $2.84 $1.00 - $1.25 Enterprise Value / Standardized Value.............................. 0.9x 1.5x 1.6x 2.6x 1.2x - 1.4x From the enterprise reference value ranges implied by applying the benchmark multiples to PetroCorp's estimated current year and 2001 estimated discretionary cash flow, estimated current year and 2001 estimated EBITDX, proved reserves and Standardized Value, Petrie Parkman determined a composite enterprise reference value range. After deducting long term debt of $34.4 million and adding net working capital of $6.2 million to the composite enterprise reference value range and dividing by the fully-diluted number of shares of PetroCorp common stock outstanding, the equity reference value range per fully-diluted share of PetroCorp common stock was $9.80 to $12.06. Relative Contribution Analysis. Using information provided to it by the management and staff of PetroCorp, with respect to PetroCorp, and prepared in conjunction with, and approved by, the management and staff of Southern Mineral, with respect to Southern Mineral, Petrie Parkman analyzed certain historical and projected operational and financial effects of the merger. In this respect, Petrie Parkman calculated relative contributions by Southern Mineral and PetroCorp to the pro forma combined entity resulting from the merger of proved reserves of Southern Mineral and PetroCorp as of October 1, 2000, estimated production for the fiscal year ended December 31, 2000, and estimated EBITDX, estimated discretionary cash flow and estimated net income for each of the fiscal years ended December 31, 2000 and ending December 31, 2001. The table below sets forth the contribution of Southern Mineral to the pro forma combined entity with respect to each of these operational and financial parameters, which can be compared (without giving effect to the cash portion of the merger consideration) with the pro forma ownership of Southern Mineral shareholders in the combined entity following the merger of up to 32% (depending on the stock elections that Southern Mineral shareholders will make). Southern Mineral's Measure Contribution ------- --------------- 2000E 2001E ------ ------ Proved Reserves (as of 10/1/00)............................ 44% N/A Production................................................. 43% N/A EBITDX..................................................... 39% 36% Discretionary Cash Flow.................................... 43% 40% Net Income................................................. 42% 39% Each analysis performed by Petrie Parkman supported its conclusion that the merger consideration was fair from a financial point of view as of the dates of its opinions to the holders of Southern Mineral common stock 45 whether such holders receive the merger consideration in cash, in PetroCorp stock or a combination of cash and PetroCorp stock. The equity value ranges of the PetroCorp common stock support the conclusion that the exchange ratio contemplated by the merger agreement implies a value within the range of fairness for the Southern Mineral common stock. The description set forth above constitutes a summary of the analyses employed and factors considered by Petrie Parkman in rendering its opinion to the Southern Mineral board. Petrie Parkman believes that its analyses must be considered as a whole and that selecting portions of its analyses, without considering all analyses and factors, could create an incomplete view of the process underlying its opinion. The preparation of a fairness opinion is a complex, analytical process involving various determinations as to the most appropriate and relevant methods of financial analysis and the application of those methods to the particular circumstances and is not necessarily susceptible to partial analysis or summary description. In arriving at its opinion, Petrie Parkman did not attribute any particular weight to any analysis considered by it, but rather made qualitative judgments as to the significance and relevance of each analysis. Any estimates resulting from the analyses are not necessarily indicative of actual values, which may be significantly more or less favorable than as set forth in this document. In addition, analyses based on forecasts of future results are not necessarily indicative of future results, which may be significantly more or less favorable than suggested by these analyses. Estimates of reference values of companies do not purport to be appraisals or necessarily reflect the prices at which companies may actually be sold. Because the estimates are inherently subject to uncertainty and based upon numerous factors or events beyond the control of the parties and Petrie Parkman, Petrie Parkman cannot assure that the estimates will prove to be accurate. No company used in the analyses of other publicly traded companies nor any transaction used in the analyses of comparable transactions is identical to Southern Mineral, PetroCorp or the proposed merger. Accordingly, these analyses must take into account differences in the financial and operating characteristics of the selected publicly traded companies and differences in the structure and timing of the selected transactions and other factors that would affect the public trading values and acquisition values of the companies considered. Petrie Parkman, as part of its investment banking business, is continually engaged in the evaluation of energy-related businesses and their securities in connection with mergers and acquisitions, negotiated underwritings, secondary distributions of listed and unlisted securities, private placements and valuations for corporate and other purposes. Southern Mineral selected Petrie Parkman as its financial advisor because it is an internationally recognized investment banking firm that has substantial experience in transactions similar to the proposed merger. Petrie Parkman has in the past provided financial advisory services to Southern Mineral in connection with Southern Mineral's bankruptcy proceedings. In addition to the transaction fee described above that Petrie Parkman will receive from Southern Mineral if the transaction with PetroCorp is consummated, since January 1, 1999, Petrie Parkman received from Southern Mineral aggregate fees of approximately $750,000. In the last two years, Petrie Parkman did not have any material relationship with PetroCorp and did not receive any fees from PetroCorp. In the ordinary course of business, Petrie Parkman or its affiliates may trade in the debt or equity securities of Southern Mineral and PetroCorp for its account and for the accounts of its customers and, accordingly, may at any time hold a long or short position in such securities. Directors and Management of PetroCorp Following the Merger After the merger, the combined companies will be known as PetroCorp and will be headquartered in Tulsa, Oklahoma. The PetroCorp management and board of directors will continue to manage the business of PetroCorp, including the business of PetroCorp Acquisition, which will succeed to the rights and obligations of Southern Mineral. PetroCorp's day-to-day operations will continue to be managed by employees of Kaiser-Francis pursuant to the management agreement with Kaiser-Francis as described further beginning on page 97. 46 Directors The following table sets forth the name and age of each current directors of Petrocorp, his principal position with PetroCorp, the year he became a director of PetroCorp and the year that his term as a director expires.

See "The Companies -- PetroCorp -- PetroCorp's Management Agreement with Kaiser-Francis" on page 97. The majority of PetroCorp's officers devote a portion of their time to companies other than PetroCorp. The allocation of officer time to PetroCorp varies depending upon the current state of PetroCorp's business including the number of transactions in progress, management and operational issues at 50 hand, and regulatory requirements which must be addressed. The following sets forth an estimated percentage of time, or range of time, currently spent by the principal officers of PetroCorp on PetroCorp business: Name Percentage of Time ---- ------------------ Gary R. Christopher 65 to 80% A.F. (Tony) Pelletier 100 Steve Berlin 15 to 35 Richard L. (Rick) Dunham 50 to 60 Craig Dolinsky 50 to 60 Ted Jacobson 5 Michael W. Moore 5 David H. Stevens 20 to 25 J. Les Watson 100 Steven E. Amos 60 to 90 Executive Compensation All of PetroCorp's principal officers, with the exception of Tony Pelletier, are employees of Kaiser-Francis helping Kaiser-Francis fulfill its management obligations under the management agreement with PetroCorp. See "The Companies - -- PetroCorp -- PetroCorp's Management Agreement with Kaiser-Francis" on page 97. In this capacity, the principal officers of PetroCorp do not receive compensation from PetroCorp, but instead receive compensation from Kaiser- Francis. This compensation reflects efforts, not only on behalf of PetroCorp, but also for the other companies they may serve, including Kaiser-Francis. For a further description of officers' allocation of time, see the relevant discussion under "Directors and Management of PetroCorp Following the Merger -- Executive and Other Officers" on page 49. Instead of paying compensation to its principal officers, rent and other overhead costs, PetroCorp pays Kaiser-Francis a management fee. For the year ended December 31, 2000, PetroCorp paid Kaiser-Francis $1,491,000 in management fees under the management agreement. Of that $1,491,000, $744,000 (or 49.9%) is considered by PetroCorp to be reimbursement of officers' salaries and expenses. The remaining 50.1% of management fees are related to other non-employee related costs and expenses. The Kaiser-Francis management fee provided in the management agreement is based on a per well rate that varies as to each type of well, without reference to any compensation paid by Kaiser-Francis to PetroCorp officers. The table below sets forth for the three fiscal years ended December 31, 2000, 1999 and 1998, all compensation paid to the chief executive officer and Mr. Pelletier by PetroCorp. All executive officers, other than Mr. Pelletier, which might otherwise be named executive officers are employees of Kaiser- Francis and are compensated by Kaiser-Francis, which in turn has a management agreement with PetroCorp.

No direct compensation is paid to Mr. Christopher by PetroCorp. He is an employee of Kaiser-Francis and is compensated by Kaiser-Francis, which in turn has a management agreement with PetroCorp. The following table sets forth certain information concerning stock options granted to Messrs. Christopher and Pelletier during the 2000 fiscal year.

(2) The options granted pursuant to 2000 awards under the PetroCorp 2000 Stock Option Plan vest and become exercisable 12 months after they are granted. Vested options are exercisable only during the 10 year period commencing on the grant date. (3) Present value at date of grant is based on the Black-Scholes Option Pricing Model adopted for use in valuing executive stock options based on the following assumptions: 41% volatility factor; underlying price of $7.06 for Mr. Christopher and $6.13 for Mr. Pelletier; option price of $7.06 for Mr. Christopher and $6.13 for Mr. Pelletier; risk free rate of return of 6% for Mr. Christopher and 6.5% for Mr. Pelletier; and no dividends. The actual value, if any, an executive may realize will depend on the excess of the stock price over the exercise price on the date the option is exercised, so there is no assurance the value realized by the named executive will be at or near the value estimated by the Black-Scholes Model. The following table sets forth certain information concerning the exercise of stock options by Messrs. Christopher and Pelletier during fiscal year 2000 and the 2000 fiscal year-end value of unexercised options.

Fuller and Wiese--In considering the recommendation of the Southern Mineral board of directors with respect to the merger, you should be aware that Messrs. Fuller and Wiese, directors of Southern Mineral, have interests in the merger which provide them with the following benefits that are in addition to their interests as shareholders of Southern Mineral. In consideration for entering into a shareholder agreement with PetroCorp, Mr. Fuller's and Mr. Wiese's stock elections, if any, will not be treated the same as other Southern Mineral shareholders if Southern Mineral shareholders make valid stock elections to receive more than 4,000,000 shares of PetroCorp stock. If such an oversubscription occurs, the stock elections of the Southern Mineral shareholders will be proportionately reduced to the extent of the oversubscription. However, PetroCorp has agreed to sell, and Messrs. Fuller and Wiese and certain of their affiliates have agreed to buy, that number of shares equal to their pro rata reduction. As a consequence, PetroCorp may issue up to approximately 108,968 shares, in addition to the 4,000,000 shares, of PetroCorp common stock to these directors in lieu of cash. Employee Retention and Severance Plan--Southern Mineral has an employee retention and severance plan which, together with employment agreements and other arrangements approved by the bankruptcy court as part of the plan of reorganization, provide for bonuses and performance incentives to be paid to certain executive officers and key employees, including all full-time employees at the time the bankruptcy plan became effective, in the event of a merger and in the event their employment is terminated in connection with the merger. Southern Mineral has an employee retention and severance plan which provides for a total of $325,000 in bonuses to be paid to certain Southern Mineral executive officers should the merger with PetroCorp be consummated. In addition, if such executive officers are terminated, without cause, by PetroCorp subsequent to the merger or if the merger results in a reduction of their responsibilities, they will also receive $487,500 in aggregate severance payments. The employee retention and severance plan expires on June 1, 2001 and requires the unanimous consent of the Southern Mineral Board to agree to any extension of the plan. Except for Messrs. Fuller and Coughlin, who will be appointed by the board to serve as directors of PetroCorp until the 2003 annual meeting, PetroCorp does not intend to retain any other members of the Southern Mineral board or any Southern Mineral employees, other than potentially certain operational employees, following the merger. New PetroCorp Directors--The Southern Mineral board has designated Mr. Coughlin and Mr. Fuller to fill the newly created vacancies, and serve until PetroCorp's 2003 annual meeting of shareholders, at which time they will be subject to being renominated as a director at the discretion of PetroCorp's board; provided, however, that if at any time after Southern Mineral's selection of such directors, either director appointed by Southern Mineral is unable to serve as a director, the other remaining Southern Mineral director will nominate and elect a replacement director. Messrs. Fuller and Coughlin will be eligible for compensation for that service. PetroCorp In August 1999, Kaiser-Francis, the largest shareholder of PetroCorp, owning 49.7% of PetroCorp's common stock outstanding as of March 13, 2001, and PetroCorp entered into a management agreement under which Kaiser-Francis agreed to provide management, technical and administrative support for all of PetroCorp's operations in the United States and Canada. In the event of the merger, Kaiser-Francis will assume these same management functions for the combined company for which it will receive additional revenue. Other than the management agreement with Kaiser-Francis, PetroCorp has not identified any interests of its directors or officers in the merger which are in conflict with those of PetroCorp shareholders. In addition, two PetroCorp officers are shareholders of Southern Mineral. Mr. Berlin, PetroCorp's chief financial officer, secretary and treasury, owns 15,0000 shares of Southern Mineral common stock. He purchased 5,000 shares in an open-market transaction on March 2, 2001 at a price of $4.10 per share and another 5,000 shares in an open-market transaction on March 8, 2001 at a price of $4.13 per share. The remaining shares have been held in a brokerage account since 1999. Mr. Dolinsky, Vice President-Land of PetroCorp, owns 5,000 Southern Mineral shares, which he purchased in an open-market transaction on March 14, 2001 at a price of $4.26 per share. 56 Our boards of directors knew about these interests, and considered them, in approving the merger and recommending that our shareholders approve the merger. PetroCorp Acquisition of Southern Mineral Shares Subsequent to the signing of the merger agreement, PetroCorp purchased shares of Southern Mineral common stock via open-market and negotiated transactions. As of March 13, 2001 PetroCorp had acquired 738,836 shares of Southern Mineral stock at an average price of $4.21 per share. As a result, PetroCorp currently owns 6% of the outstanding shares of Southern Mineral stock. PetroCorp will have the ability to vote its shares at the special meeting, but will not be eligible to receive any merger consideration pursuant to the terms of the merger agreement. Legal Proceedings Southern Mineral is, from time to time, a party to litigation arising in the normal course of its business operations. Based on information currently available, management of Southern Mineral believes that it is not a party to any litigation the results of which it expects to have a material adverse effect on its business, financial position or results of operations. PetroCorp is, from time to time, a party to litigation arising in the normal course of its business operations. Based on information currently available, management of PetroCorp believes that it is not a party to any litigation the results of which it expects to have a material adverse effect on its business, financial position or results of operations. Cancellation, Delisting and Deregistration of Southern Mineral Common Stock If the merger is completed, the shares of Southern Mineral common stock will be cancelled, delisted from the OTC Bulletin Board and deregistered under the Exchange Act. After the merger, holders of Southern Mineral warrants will be entitled to receive for each share of Southern Mineral stock underlying such warrant the per share merger consideration in cash, without interest, after payment of any applicable exercise price. PetroCorp's stock will continue to be listed on the AMEX under the trading symbol "PEX." Federal Securities Law Consequences All shares of PetroCorp common stock that Southern Mineral shareholders will receive in the merger will be freely transferable, except for shares of PetroCorp common stock that are received by persons who are deemed to be "affiliates" of Southern Mineral under the Securities Act at the time of the Southern Mineral shareholder meeting. These affiliates may resell the shares of PetroCorp common stock they receive in the merger only in transactions permitted by Rule 145 under the Securities Act or as otherwise permitted under the Securities Act. Persons who may be deemed to be affiliates of Southern Mineral for the above purposes generally include individuals or entities that control, are controlled by or are under common control with Southern Mineral, and include directors and certain executive officers of Southern Mineral. The merger agreement requires that Southern Mineral use commercially reasonable efforts to cause each of these affiliates to deliver to PetroCorp, within 30 days of the date of entering into the merger agreement (and in any event prior to the effective time), a written agreement to the effect that these persons will not sell, transfer or otherwise dispose of any of the shares of PetroCorp common stock issued to them in the merger in violation of the Securities Act or the related SEC rules. A copy of the form affiliate letter is attached as Annex VII. This document does not cover any resales of the PetroCorp common stock received in the merger, and no person is authorized to make any use of this document in connection with any such resales. 57 THE MERGER AGREEMENT The following summarizes the material terms of the merger agreement, a copy of which we have attached as Annex I to this document and is incorporated herein by reference. We urge you to read the merger agreement in its entirety for a more complete description of the terms and conditions of the merger. The Merger Under the merger agreement, Southern Mineral will merge into PetroCorp Acquisition, a wholly-owned subsidiary of PetroCorp. The merger will become effective when we have filed certificates of merger with the Secretaries of State of Delaware and Nevada. We will make such filings shortly after the end of the Southern Mineral shareholders' stock election period further described below under "Southern Mineral Stock Elections; Minimum and Maximum Share Issuances" or, if later, after the last of the conditions precedent to the merger set forth in the merger agreement has been satisfied or waived. Conversion of Southern Mineral Shares At the effective time of the merger: . each issued and outstanding share of Southern Mineral stock (excluding shares held in treasury or owned by PetroCorp or its subsidiaries) will be converted into the right to receive the per share merger consideration of $4.71 in cash or, if the shareholder timely elects, in PetroCorp common stock based on an exchange ratio of .471. . each share of Southern Mineral stock will be cancelled, delisted and deregistered. . each warrant to purchase shares of Southern Mineral stock outstanding immediately prior to the effective time of the merger will remain outstanding and will be assumed by PetroCorp and PetroCorp Acquisition and represent the right to receive, upon exercise of such warrant (including the payment of the applicable exercise price), an amount of cash (without interest) equal to the product of the number of Southern Mineral shares underlying such warrant immediately prior to the effective time of the merger, multiplied by the per share merger consideration of $4.71, being the amount of merger consideration such holder would have been entitled to receive had such warrant holder become a Southern Mineral shareholder immediately prior to the effective time of the merger. . each option to purchase shares of Southern Mineral stock outstanding immediately prior to the effective time of the merger will remain outstanding and will be assumed by PetroCorp and converted into an option to purchase a number of shares of PetroCorp stock equal to the product of the number of Southern Mineral shares underlying such option multiplied by the exchange ratio of .471, unless the option holder elects by written notice to Southern Mineral prior to the effective time of the merger to receive cash; in which case, the option will represent the right to receive an amount in cash equal to the product of the number of shares underlying the option multiplied by the positive difference, if any, between the per share merger consideration of $4.71 and the exercise price. Under Nevada law, Southern Mineral shareholders may be entitled to exercise dissenter's rights and to receive an appraisal of the value of their shares. See "The Merger -- Dissenter's Rights." Southern Mineral Stock Elections; Minimum and Maximum Share Issuances If PetroCorp and Southern Mineral shareholders each approve the merger, Southern Mineral shareholders will be sent a stock election form shortly after the Southern Mineral shareholders meeting. Each Southern Mineral shareholder desiring to receive any portion of its merger consideration in the form of PetroCorp stock will need to deliver a valid stock election form to PetroCorp's exchange agent within 20 days following the date on which the forms were mailed - -- PetroCorp will publicly announce this date once it is established -- and until that time any election may be changed. Southern Mineral and PetroCorp may agree to extend the final deadline for receipt of stock elections. 58 If Southern Mineral shareholders do not elect to receive at least 3,000,000 shares of PetroCorp stock, PetroCorp's conditions to closing will not be satisfied and PetroCorp will not be obligated to close the merger, although PetroCorp could waive that condition. For additional information, refer to "Conditions to Closing" below. If Southern Mineral shareholders elect to receive more than 4,000,000 shares of PetroCorp stock in the merger, the 4,000,000 shares of PetroCorp stock available for issuance will be prorated among shareholders electing to receive stock, and PetroCorp has agreed to sell up to 108,968 shares, in addition to the 4,000,000 shares, to two Southern Mineral directors, Messrs. Fuller and Wiese, who have agreed to buy that number of shares equal to their pro rata reduction in connection with entering into shareholder agreements agreeing to support the merger. For example, if Southern Mineral shareholders elect to receive 5,000,000 PetroCorp shares in the merger, each shareholder electing stock will receive only 80% (4,000,000 / 5,000,000) of the number of PetroCorp shares requested. Any merger consideration that is not paid in PetroCorp stock will be paid in cash. Exchange of Shares As soon as practicable after the effective time of the merger, the exchange agent will mail you a letter of transmittal and instructions for exchanging your Southern Mineral stock certificates for cash, or, if a proper election is made, PetroCorp stock or a combination of cash and PetroCorp stock. PetroCorp's exchange agent is Corporate Stock Transfer, Inc. Holders of Southern Mineral stock will not be entitled to receive any dividends or other distributions payable by PetroCorp until their Southern Mineral certificates are surrendered for exchange as provided in the merger agreement. Upon surrender, however, such holders will receive accumulated dividends and distributions without interest. Holders of unexchanged shares of Southern Mineral stock will have no further claim upon the exchange agent six months after the effective time of the merger or for such longer time as PetroCorp determines and will thereafter look only to PetroCorp and PetroCorp Acquisition for payment in respect of Southern Mineral shares. Fractional shares of PetroCorp stock will not be issued to holders of Southern Mineral stock. For each fractional share of PetroCorp stock that would otherwise be issued, the holder will instead receive an amount of money equal to such fraction multiplied by the cash per share merger consideration of $4.71. Director Nominees PetroCorp has amended its bylaws to create two vacancies on its board upon the effective time of the merger, which will be filled by Messrs. Fuller and Coughlin, persons selected by Southern Mineral's board of directors to serve from the effective time of the merger until the second annual meeting of PetroCorp shareholders after the effective time of the merger. If one of Southern Mineral's board representatives ceases to serve on PetroCorp's board of directors for any reason, the remaining Southern Mineral board representative will appoint his successor. Representations and Warranties The merger agreement contains various representations and warranties of PetroCorp and Southern Mineral, relating, among other things, to the following: . their incorporation, existence, good standing, capitalization, corporate power and similar corporate matters; . their authorization, execution, delivery and performance and the enforceability of the merger agreement and related agreements; . the absence of conflicts, violations and defaults under their certificate or articles of incorporation and bylaws and other material agreements and documents; 59 . the documents and reports filed with the SEC and the accuracy and completeness of the information contained therein; . compliance with environmental laws; and . certain matters regarding the oil and gas properties and operations of each party. All representations and warranties of PetroCorp and Southern Mineral expire at the effective time of the merger, or, if sooner, the termination of the merger agreement, subject to any claims a party may have under the merger agreement. Material Covenants Conduct of Business Pending the Merger From the date of the merger agreement until the closing, Southern Mineral and PetroCorp have agreed to continue to operate their respective businesses according to their customary course of business, subject to exceptions included in the merger agreement. Additional Covenants The merger agreement also provides that, from the date of the merger agreement until the closing, Southern Mineral and PetroCorp will not, without the consent of the other: . declare, set aside, authorize or pay any dividend or other distribution; . split, combine or reclassify their outstanding stock or issue or authorize or propose the issuance of any other securities in respect of or in substitution for any of their shares; . redeem, acquire, or otherwise encumber any of their, or of their subsidiaries, shares, or any rights, warrants or options to acquire any such shares or other securities, other than the issuance of shares upon the exercise of options or warrants outstanding on the date of the merger agreement; . amend their charter or bylaws; . merge or consolidate with, or purchase a substantial equity interest in, any other entity or make any acquisition of assets, except that Southern Mineral may engage in such transactions to the extent they do not exceed $100,000 individually or $3,000,000 in the aggregate, and PetroCorp may engage in such transactions to the extent they are not material to PetroCorp; . sell, lease, license, mortgage or otherwise encumber, any of their assets, other than transactions that are in the ordinary course of business consistent with past practice and not material to such party; . incur any indebtedness other than indebtedness incurred in the ordinary course of business consistent with past practice that is prepayable at any time without premium or penalty; or . enter into, amend, terminate or waive any provision of, any agreement or arrangement with any related party. Additionally Southern Mineral has agreed not to take any of following actions without the consent of PetroCorp: . enter into or adopt any new, or amend any existing, severance plan or arrangement, or any existing employee benefit plan or employment or consulting agreement; . alter its corporate structure or ownership; . increase the compensation payable or to become payable to its officers or employees; 60 . grant or award any stock options or other equity-based incentive awards other than to directors and employees; . take any action with respect to accounting policies or procedures for tax or accounting purposes, or make or change any election with respect to taxes, except that Southern Mineral can elect to forgo the carryback of net operating losses; . make or agree to make any new capital expenditure in excess of $100,000 individually or $3,000,000 in the aggregate except for capital expenditures in the ordinary course of business consistent with past practice to repair or replace casualty losses; . pay, discharge or satisfy any claims, liabilities or obligations, other than in the ordinary course of business consistent with past practice or in accordance with their terms; or . settle or compromise any material federal, state, local or foreign tax liability. Other Agreements The merger agreement contains covenants and agreements of PetroCorp and Southern Mineral customary for transactions like the merger relating to, among other things: . the preparation of the registration statement of which this document is a part, and including in this document the recommendation by Southern Mineral and PetroCorp's boards that their respective shareholders vote to approve the merger; . listing of the PetroCorp stock to be issued pursuant to the merger on the AMEX; . Southern Mineral using commercially reasonable efforts to cause each of its affiliates, which generally includes Southern Mineral officers, directors and holders of at least 5% of the outstanding shares of its common stock, to execute and deliver to PetroCorp an affiliate agreement prior to the effective time of the merger wherein each of Southern Mineral's affiliates will agree to comply with the applicable requirements of Rule 145; . if any "fair price," "moratorium," "control share acquisition" or other form of antitakeover statute or regulation becomes applicable to the transactions contemplated by the merger agreement, each party will take any actions as are commercially reasonable so that the merger may close as promptly as practicable; and . each party using best efforts to consummate the merger. Employee Matters Neither PetroCorp nor any Southern Mineral employee will be obligated to continue any employment relationship or any specific terms of employment for any specific period of time after the merger. PetroCorp does not anticipate continuing to employ any Southern Mineral employees following the merger, other than potentially certain operational employees. PetroCorp will sponsor Southern Mineral's employee benefit plans after the merger, and will satisfy all obligations under Southern Mineral's employee benefit plans. After the merger, PetroCorp may amend, modify or terminate any Southern Mineral employee benefit plans. To the extent PetroCorp makes available any of its employee benefit plans, programs or policies to any Southern Mineral employee: . PetroCorp will credit service with Southern Mineral for eligibility and vesting purposes and for purposes of qualifying for any additional benefits tied to periods of service under such plan, program or policy; and . PetroCorp will cause any welfare benefit plans to provide credit for any copayments or deductibles by such employees and waive all pre-existing condition exclusions and waiting periods. 61 At the reasonable request of PetroCorp, Southern Mineral will amend or terminate any of its employee benefit plans at or immediately prior to the effective time of the merger (whichever PetroCorp may request) and will take such other steps as PetroCorp may reasonably request to facilitate the administration after the effective time of the merger of PetroCorp's compensation and benefit plans, programs and arrangements. Within 30 days after the effective time of the merger, PetroCorp will file a registration statement on Form S-8 or other appropriate form with the SEC to register PetroCorp stock issuable upon exercise of the assumed Southern Mineral options and will use commercially reasonable efforts to cause the registration statement to remain effective, and to maintain the current status of the prospectus or prospectuses contained therein, until the exercise or expiration of the options. Indemnification PetroCorp will indemnify the present and former directors, officers and employees of Southern Mineral and its respective subsidiaries against all losses, damages, costs, expenses and liabilities arising out of the transactions contemplated by the merger agreement existing at or before the effective date of the merger, including actions taken in connection with the merger. All indemnification in favor of such person under Southern Mineral's charter documents will remain in effect. PetroCorp will also be obligated to advance expenses pursuant to reimbursement agreements. For six years after the effective date of the merger, PetroCorp will maintain Southern Mineral's existing directors' and officers' liability insurance policies covering the existing directors and officers to the extent related to liabilities prior to the merger. The coverage will be at least as favorable as the existing coverages, but PetroCorp will not be required to spend over 200% of the annual premium paid by Southern Mineral for its existing coverage. No Solicitation Southern Mineral has agreed that it will immediately cease and cause to be ceased any existing activities, discussions or negotiations for a merger or similar transaction and it will not solicit, initiate or encourage any proposal for a merger or similar transaction. This includes engaging in negotiations with or giving any nonpublic information to any person that has made or may be considering making such a proposal. However, if required by their fiduciary duties under law, the merger agreement permits Southern Mineral to furnish information to, and enter into negotiations with, any party that makes an unsolicited proposal for a merger or similar transaction if the Southern Mineral board has determined that the proposal is superior from a financial point of view, and the board determines in good faith that it is required to investigate further such proposal to comply with its fiduciary duty imposed by law. Southern Mineral has agreed to inform PetroCorp of any merger or similar proposal or any discussions or negotiations regarding such a proposal. Southern Mineral has also agreed to use all reasonable efforts to keep PetroCorp informed of the status and terms of any developments with respect to such discussions or negotiations. If Southern Mineral accepts a superior proposal (as more particularly described in the merger agreement) and terminates the merger agreement, it must pay PetroCorp $2,350,000. In addition, PetroCorp will have the right to terminate the merger agreement if Southern Mineral fails to reject such an offer within 30 days, but in such an instance, neither party will pay any termination or break-up fee. Conditions to Closing The obligations of PetroCorp and Southern Mineral to effect the merger are subject to fulfillment or waiver of the following conditions: . the effectiveness of the registration statement of which this document is a part; 62 . the absence of any preliminary or permanent injunction or order by any federal or state court in the United States of competent jurisdiction prohibiting the consummation of the merger; . approval for listing on the AMEX of the PetroCorp shares to be issued in the merger; and . approval of the merger by the PetroCorp shareholders and the Southern Mineral shareholders. The obligation of Southern Mineral to effect the merger is also subject to the fulfillment of the following conditions: . the accuracy of the representations and warranties of PetroCorp, without regard to materiality qualifiers, unless such inaccuracy would not have a material adverse effect on PetroCorp or its subsidiaries and PetroCorp having performed in all material respects its obligations and covenants; . PetroCorp obtaining all consents, waivers, approvals, authorizations or orders required for the consummation of the merger, except for those which would not reasonably be expected to adversely affect the closing of the merger; and . PetroCorp having no change in its financial condition, business or operations which amounts to a material adverse effect on its business. The obligation of PetroCorp to effect the merger is also subject to the fulfillment of the following conditions, any of which may be waived by PetroCorp: . the accuracy of the representations and warranties of Southern Mineral, without regard to materiality qualifiers, unless such inaccuracy would not have a material adverse effect on Southern Mineral or its subsidiaries and Southern Mineral having performed in all material respects its obligations and covenants; . Southern Mineral obtaining all consents, waivers, approvals, authorizations or orders required for the consummation of the merger, except for those which would not reasonably be expected to adversely affect the closing of the merger; . Southern Mineral having no change in its financial condition, business or operations which amounts to a material adverse effect on its business; and . Southern Mineral shareholders having elected to receive at least 3,000,000 PetroCorp shares in the merger. Termination Southern Mineral and PetroCorp may terminate the merger agreement by mutual written consent. In addition, either party may terminate the agreement as follows: . if the other party is in material breach of the merger agreement and this breach is not cured in all material respects within 10 business days after notice of the breach; . if a statute, rule, regulation or executive order will have been enacted prohibiting the consummation of the merger substantially on the terms contemplated by the merger agreement; . if a final and non-appealable order, decree, ruling or other act of a court or other competent authority restrains or prevents the consummation of the merger; . if the PetroCorp or Southern Mineral shareholders fail to approve the merger at a duly held meeting of shareholders; or . if the merger has not been consummated on or before May 31, 2001. In addition, Southern Mineral has the right to terminate the merger agreement if the Southern Mineral board has received a superior proposal which the board of directors has resolved to accept, and PetroCorp may 63 terminate the merger agreement if the Southern Mineral board fails to reject a superior proposal within 30 days of receipt. If the merger agreement is terminated by PetroCorp other than for a breach by Southern Mineral of its representations, warranties, covenants or agreements, PetroCorp has agreed not to make an attempt to acquire the securities of Southern Mineral for two years following the termination of the merger agreement. Termination Fees and Expenses If Southern Mineral terminates the merger agreement because it is accepting a superior proposal, it is required to pay PetroCorp $2,350,000. PetroCorp will pay Southern Mineral $250,000 if the merger does not occur for any reason other than: . a breach by Southern Mineral of its representations, warranties, covenants or obligations under the merger agreement; . Southern Mineral shareholders failing to approve the merger at a duly held meeting of shareholders; . Southern Mineral or PetroCorp having a material adverse change in their financial conditions, businesses or operations; . Southern Mineral not obtaining the necessary consents and waivers to consummate the merger; or . PetroCorp electing to terminate the merger agreement because the Southern Mineral board has not rejected a superior proposal within 30 days of receipt. If the merger agreement is terminated by reason of a willful breach by a party of its representations, warranties, covenants or agreements, in addition to other remedies available to the non-breaching party, the breaching party will be required to reimburse the non-breaching party for all out-of-pocket costs and expenses incurred by the non-breaching party in connection with the merger. Amendment and Waiver The merger agreement may be amended or supplemented in writing before the effective time of the merger by Southern Mineral and PetroCorp except as otherwise provided by law. The law provides that after the PetroCorp and Southern Mineral shareholders approve the merger, there may not be any change materially adverse to the PetroCorp or Southern Mineral shareholders without further approval of the PetroCorp and Southern Mineral shareholders, as applicable. Amendment No. 1 to Merger Agreement On March 13, 2001, PetroCorp and Southern Mineral agreed to amend the merger agreement as follows: . The condition to the parties' obligation to close that the parties receive an opinion of counsel that the merger would qualify as a tax- free reorganization under Section 368 of the Internal Revenue Code of 1986 was removed. . The condition to Southern Mineral's obligation to close that its shareholders elect to receive at least 3,000,000 shares of PetroCorp stock was removed. . The potential adjustments to the merger consideration based on Southern Mineral's transaction costs was removed. Such amendments were intended to eliminate uncertainties regarding the closing of the merger and simplify the decision for each party's shareholders. 64 OTHER AGREEMENTS Southern Mineral Shareholder Agreements In connection with the execution and delivery of the merger agreement, PetroCorp entered into shareholder agreements with Messrs. Fuller, Wiese and Coughlin, who are directors and shareholders of Southern Mineral, and persons and entities related to them. The Fuller group owned 105,861 shares and options and warrants for an additional 143,027 shares; the Wiese group owned 103,341 shares and options and warrants for an additional 141,512 shares; and the Coughlin group owned 1,730,243 shares of the 12,231,934 shares of Southern Mineral stock outstanding on March 13, 2000. These shareholders agreed: . to vote their shares of Southern Mineral stock in favor of the merger; . not to solicit alternative takeover proposals for Southern Mineral; and . not to sell or otherwise dispose of any of their shares of Southern Mineral stock. The agreements signed by the Wiese and Fuller groups also have the effect of ensuring that, if Southern Mineral shareholders make valid stock elections to receive more than 4,000,000 shares of PetroCorp stock, the stock elections of these two groups will not be prorated downward. As a consequence, PetroCorp may issue up to approximately 108,968 additional shares of PetroCorp common stock to these shareholders in lieu of cash. The shareholder agreements terminate upon the earlier to occur of the completion of the merger or the termination of the merger agreement in accordance with its terms. PetroCorp Shareholder Agreements In connection with the execution and delivery of the merger agreement, Southern Mineral entered into shareholder agreements with St. Paul Fire and Marine Insurance Company and Kaiser-Francis. St. Paul owned 1,738,500 shares, and Kaiser-Francis owned 4,327,457 shares of the 8,720,619 shares of PetroCorp stock outstanding on March 13, 2001. These shareholders agreed: . to vote their shares of PetroCorp stock in favor of the merger; . not to solicit alternative proposals for a PetroCorp merger or consolidation; and . not to sell or otherwise dispose of any of their shares of PetroCorp stock. The shareholder agreement signed by Kaiser-Francis also stipulates that Kaiser-Francis will amend its management agreement with PetroCorp by removing the provisions granting Kaiser-Francis royalties on new oil and gas prospects in exchange for being compensated for certain services to be rendered by Kaiser-Francis which are currently not contemplated in the management agreement. In the shareholder agreement signed by St. Paul, Southern Mineral agreed that its two nominees to be selected to serve on the PetroCorp board after the merger will not have served as executive officers of Southern Mineral. The shareholder agreements terminate upon the earlier to occur of the completion of the merger or the termination of the merger agreement in accordance with its terms. Shelf Registration Pursuant to shareholder agreements and affiliate letters, PetroCorp must file and have effective by the merger closing date, a shelf registration statement pursuant to Rule 415 of the Securities Act registering the transfer of the shares they received by Messrs. Fuller, Wiese and Coughlin and other Southern Mineral affiliates in the merger, subject to blackout periods imposed by underwriters of any underwritten offerings and other limitations. 65 COMPARISON OF SHAREHOLDERS' RIGHTS As a result of the merger, the holders of Southern Mineral common stock who elect to receive PetroCorp stock will become holders of PetroCorp common stock. The rights of the shareholders of PetroCorp will be governed by applicable Texas law, including the Texas Business Corporation Act, and by PetroCorp's articles of incorporation and bylaws. Southern Mineral shareholders will cease to be governed by applicable Nevada law and the articles of incorporation and bylaws of Southern Mineral. The following summarizes the material differences between the rights of PetroCorp shareholders and Southern Mineral shareholders. The following summaries do not purport to provide a complete description of the specific rights of PetroCorp shareholders under Texas law and PetroCorp's articles of incorporation and bylaws, as compared with the rights of Southern Mineral shareholders under Nevada law, Southern Mineral's articles of incorporation and bylaws. These summaries are qualified in their entirety by reference to the governing corporate instruments of PetroCorp and Southern Mineral to which shareholders are referred and the applicable Texas and Nevada laws. PetroCorp Southern Mineral --------- ---------------- Authorized Capital Stock The total number of authorized shares of capital stock of PetroCorp is 26,000,000, consisting of 25,000,000 shares of common stock, par value $0.01 per share, and 1,000,000 shares of preferred stock, par value $0.01 per share. The total number of authorized shares of capital stock of Southern Mineral is 80,000,000, consisting of 75,000,000 shares of common stock, par value $0.01 per share, and 5,000,000 shares of preferred stock, par value $0.01 per share. Directors Under Texas law, the board of directors consists of one or more members, which number is stated in the articles of incorporation or bylaws. The number may by changed by amendment to the articles of incorporation or bylaws, or as provided in the articles of incorporation. Texas law permits, but does not require, a classified board of directors with staggered terms under which the board of directors is divided into two or three classes as nearly equal as possible and are elected for terms of two or three years, respectively. The board of directors of PetroCorp currently has seven members, which number will be increased to nine at the effective time of the merger. Pursuant to the merger agreement, Messrs. Fuller and Coughlin of Southern Mineral will be added to PetroCorp's board for a total of nine members. The PetroCorp board of directors is divided into three separate classes, consisting, as nearly as possible, of equal numbers of directors, with one class being elected annually. Nevada law permits, but does not require a classified board of directors with staggered terms. Southern Mineral's bylaws do not create a classified board of directors. The Southern Mineral board of directors has seven members. The Southern Mineral bylaws provide that the Southern Mineral board of directors will consist of seven members until the first annual or special meeting after August 1, 2001, and thereafter the Southern Mineral board of directors may, by resolution, increase or decrease the number of directors, provided that: . such number shall be no more than twelve and shall be at least one, and . no amendment to the Bylaws may shorten the term of any incumbent director. 66 PetroCorp Southern Mineral --------- ---------------- Removal of Directors Under Texas law, a corporation may provide for the removal of a director or the entire board of directors with or without cause in its articles of incorporation or bylaws. Under the PetroCorp bylaws, any director or the entire board of directors may be removed with or without cause by the holders of two-thirds of the shares then entitled to vote at an election of directors. Under Nevada law, any director or the entire board may be removed, with or without cause, by the holders of a two-thirds majority of the shares then entitled to vote at an election of directors. In addition, if the holders of a class or series of shares are entitled to elect a director, then removal is by two-thirds vote of that class. Under the Southern Mineral articles of incorporation, any director, may be removed from office only at a meeting of shareholders called for such purpose, and by the affirmative vote of holders of not less than two-thirds of the then holders of that class or series of stock. Filling Vacancies of the Board of Directors Under Texas law, any vacancy occurring in the board of directors may be filled by the shareholders or by the affirmative vote of a majority of the remaining directors, although less than a quorum. A directorship to be filled by reason of an increase in the number of directors may be filled by the shareholders or by the board of directors for a term of office continuing only until the next election of one or more directors by the shareholders, provided that the board of directors may not fill more than two such directorships during the period between any two successive annual meetings of shareholders. If shareholders of any class or series of shares or group of classes or series of shares are entitled to elect any directors, any vacancies may be filled by a majority vote of the directors elected by such class, series, or group remaining in office or by vote of the shareholders of the outstanding shares of such class, series, or group. The PetroCorp bylaws provide that the PetroCorp board of directors will be fixed at seven and then may be increased or decreased from time to time by amendment of the bylaws. Amendment of the bylaws may occur through the affirmative vote of not less than two thirds of the shareholders entitled to vote or an affirmative vote of a majority of directors in office. The PetroCorp board of directors is divided into three separate classes, consisting, as nearly as possible, of equal numbers of directors, with one class being elected annually.The PetroCorp bylaws provide that Under Nevada law, unless otherwise provided in the articles of incorporation, vacancies, including those caused by newly-created directorships, may be filled by a majority of the remaining directors then in office, even if the remaining directors do not constitute a quorum. Except for the rights relating to any series of preferred stock to elect directors, the Southern Mineral articles of incorporation provide that newly created directorships resulting from any increase in the authorized number of directors, and any vacancies on the board resulting from death, resignation, disqualification, removal or other cause, may be filled only by the affirmative vote of a majority of the remaining directors then in office, even though less than a quorum. 67 PetroCorp Southern Mineral --------- ---------------- vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled only by the affirmative vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director. The bylaws further provide that if the PetroCorp articles of incorporation entitle the holders of any class or classes of stock or series thereof to elect one or more directors, vacancies and newly created directorships of such class or classes or series may be filled only by a majority of the directors elected by such class or classes or series thereof then in office, or by a sole remaining director so elected. Both the PetroCorp bylaws and the Southern Mineral articles of incorporation provide that any director elected to fill vacancies or newly created directorships shall hold office for the remainder of the full term of the class of directors in which the new directorship was created or the vacancy occurred and until such director's successor has been elected and qualified. Amendment of Bylaws Under Texas law, the board of directors may amend, repeal or adopt a corporation's bylaws, unless the articles of incorporation reserve this power exclusively to the shareholders, or the shareholders in amending, repealing or adopting a particular bylaw expressly provide that the board of directors may not amend or repeal that bylaw. A corporation's shareholders may always amend, repeal or adopt the corporation's bylaw even though the bylaws may be amended, repealed or adopted by the board of directors, unless the articles of incorporation or bylaws provide otherwise. The PetroCorp articles of incorporation expressly authorize the PetroCorp board of directors to adopt, amend or repeal the bylaws of the corporation, without any action on the part of the shareholders. However, bylaws adopted or amended by the board and any powers thereby conferred may be amended, altered, or repealed by at least a majority vote of the shareholders. Under Nevada law, the directors are authorized to adopt, amend and repeal the bylaws, subject to bylaws, if any, adopted by shareholders. In addition to any affirmative vote required by law, the Southern Mineral articles of incorporation provided the bylaws may be altered, amended, repealed or rescinded by either . an affirmative vote of at least a majority of the then-authorized board of directors, or . by a majority vote of the shareholders. 68 PetroCorp Southern Mineral --------- ---------------- Amendment of Articles Under Texas law, an amendment to the articles of incorporation requires the approval of the holders of at least two-thirds of the outstanding shares of the corporation entitled to vote on the matter. The articles of incorporation may provide for a different vote, but not less than a majority of the shares entitled to vote on that matter. The PetroCorp articles do not so provide and thus changes to the PetroCorp articles of incorporation requires a two thirds vote of the shareholders. Under Nevada law, a corporation's board and its shareholders may amend the corporation's articles of incorporation if the board of directors recommends the amendment and the holders of at least a majority of shares of stock entitled to vote approve the amendment. In addition to any affirmative vote required by law, the Southern Mineral articles of incorporation may be altered, amended, repealed or rescinded by at least a majority vote of the then-combined voting power of the then-outstanding voting stock (common and preferred stock, voting pursuant to the terms of such preferred stock); provided however that any change to Articles II (Definitions), VI (Election of Directors) or VII (Amendment of Corporate Documents) requires a vote of at least two-thirds of the voting stock unless the proposed change has been recommended by at least two-thirds of the then- authorized number of directors. Notwithstanding any provisions in the articles to the contrary, if any proposed amendment would alter or change any preference or any relative or other right given to any class or series of outstanding shares, then the amendment must be approved by the vote, in addition to the affirmative vote otherwise required, of the holders of shares representing a majority of the voting power of each class or series affected by the amendment regardless of limitations or restrictions on the voting power of such class. 69 PetroCorp Southern Mineral --------- ---------------- Shareholder Meetings Under Texas law, the president, the board of directors, other persons authorized in the bylaws or articles of incorporation, or the shareholders of not less than 10% of all of the shares entitled to vote have the right to call a special shareholders' meeting, unless the articles of incorporation provide for a number of shares greater than or less than 10%, in which event, special meetings of the shareholders may be called by the holders of at least the percentage of shares so specified in the articles of incorporation, but in no event may the articles of incorporation provide for a number of shares greater than 50% that would be required to call a special meeting. The PetroCorp articles do not alter the statutory rule described herein. Its bylaws provide that a special meeting of the shareholders may be called by the chairman of the board and chief executive officer, the president, any one of the directors or holders of at least 10% of all the shares entitled to vote at the proposed special meeting. Nevada law provides no separate provision for the calling of a special meeting. Special meetings are called in accordance with the bylaws of the company or the requirements of a specific provision of Nevada law. The Southern Mineral bylaws provide that special meetings of shareholders may be called by the president and shall be called by the president or secretary at the request in writing of a majority of the board of directors, or at the request in writing of shareholders owning a majority in amount of the entire capital stock of the corporation issued and outstanding and entitled to vote. Quorum Under Texas law, with respect to any action by the directors, a majority of the number of directors fixed by the articles of incorporation or the bylaws shall constitute a quorum for the transaction of business. With respect to any meeting of shareholders, a quorum shall be present if the holders of a majority of the shares entitled to vote at the meeting are represented at the meeting in person or by proxy. Pursuant to both the PetroCorp bylaws and the Southern Mineral bylaws, a quorum for the transaction of business at any meeting of the board of directors consists of a majority of the entire board of directors. Under Nevada law, unless the articles of incorporation or bylaws provide otherwise, a majority of the directors then in office constitute a quorum. With respect to meetings of shareholders, unless the articles of incorporation or bylaws provide otherwise, a majority of the voting power, present in person or by proxy, constitutes a quorum. Under both the PetroCorp and Southern Mineral bylaws, a quorum for the transaction of business at any shareholder meeting consists of the holders of a majority of the shares of voting stock issued and outstanding and entitled to vote, present in person or represented by proxy. 70 PetroCorp Southern Mineral --------- ---------------- Preemptive Rights Under Texas law, shareholders of a corporation have a preemptive right to acquire additional, unissued, or treasury shares of the corporation, or securities of the corporation convertible into or carrying a right to subscribe to or acquire shares, except to the extent limited or denied by statute or by the articles of incorporation. Under Nevada law, for corporations organized before October 1, 1991, except to the extent limited or denied by the articles of incorporation, shareholders have a statutorily limited preemptive right to acquire unissued shares, treasury shares, or securities convertible into such shares. Both the PetroCorp and Southern Mineral articles of incorporation expressly deny preemptive rights. Voting by Shareholders Under Texas law, with respect to any action to be taken by the shareholders of a corporation, a vote of the majority of the shares entitled to vote and represented at a meeting at which a quorum is present shall be sufficient to take action, unless the vote of a greater number is required by law, articles of incorporation or bylaws. Under the PetroCorp bylaws, unless otherwise required by law, the PetroCorp articles of incorporation or the PetroCorp bylaws, action by PetroCorp shareholders is taken by the vote of the holders of a majority of the votes cast at a meeting of shareholders at which a quorum is present. Under Nevada law, with respect to any action taken by the stockholders of the corporation other than the election of directors, unless otherwise provided in the articles of incorporation or the bylaws, the action is taken if at a meeting which a quorum is present the votes cast in favor of the action exceed those against it. Directors are elected by a plurality. Pursuant to the Southern Mineral bylaws, action by Southern Mineral shareholders is taken by the vote of the holders of a majority of the stock represented and entitled to vote at a shareholders meeting at which a quorum is present, subject to applicable law, the Southern Mineral articles of incorporation or the Southern Mineral bylaws. Nevada's control share act, Sections 78.378 through 78.3793 of Nevada Revised Statutes, generally prohibits an acquirer from voting newly acquired shares of a Nevada corporation's stock after crossing the threshold ownership percentages of at least one-fifth but less than one-third, at least one-third but less than a majority, and a majority or more of all of the outstanding voting power, unless the acquirer obtains the approval of the corporation's stockholders, excluding shares as to which the acquirer exercises voting rights. The thresholds are computed based on the number of shares directly or indirectly held by the acquirer individually or in association with others. The control share act only applies to Nevada corporations doing business directly or through an affiliated corporation in Nevada with at least 200 stockholders of record, at least 100 of whom have addresses in Nevada. The act applies to all such corporations unless the articles of incorporation or bylaws in effect on the 71 PetroCorp Southern Mineral --------- ---------------- tenth day following the crossing the thresholds described above provide otherwise. If the corporation's articles or bylaws in effect on such tenth day so provide, the corporation may call for redemption certain of the acquirer's shares if the stockholders do not grant full voting rights or the acquirer fails to timely deliver information to the corporation. Unless the articles of incorporation or bylaws in effect on the tenth day following acquisition of such majority provide otherwise, if an acquirer's shares are accorded full voting rights and the acquirer has acquired control shares with at least a majority of all the voting power, any stockholder of record who has not voted for approval of voting rights is entitled to demand payment for the fair value of his or her shares, which is generally not less than the highest price per share paid in the transaction subjecting the acquirer to the control share act. Cumulative Voting Under Texas law, cumulative voting is available unless prohibited by a corporation's articles of incorporation. The Petrocorp articles of incorporation prohibit cumulative voting in any matter; therefore, the shareholders do not have a right to cumulative voting. Under Nevada law, articles of incorporation may provide for cumulative voting in director elections. In order to exercise the right of cumulative voting, one or more of the shareholders requesting cumulative voting must give written notice that cumulative voting is desired, in advance of the meeting, to the president or the secretary of the corporation. Since Southern Mineral's articles of incorporation are silent regarding cumulative voting, Southern Mineral does not have cumulative voting. 72 PetroCorp Southern Mineral --------- ---------------- Shareholder Action without a Meeting Under Texas law, any action that may be taken at a meeting of the shareholders may be taken without a meeting if written consent thereto is signed by all the holders of shares entitled to vote on the action. The articles of incorporation of a Texas corporation may provide that action by written consent in lieu of a meeting may be taken by the holders of that number of shares which, under the corporation's articles of incorporation, would be required to take the action which is the subject of the consent at a meeting at which the holders of all shares entitled to vote on the action were present and voted. The PetroCorp bylaws provide for any action which may be taken at a shareholder meeting to be taken without a meeting if written consent or consents setting forth the action to be taken are signed by shareholders of all the shares entitled to vote on the action. Under Nevada law, unless otherwise provided in the articles of incorporation or the bylaws, any action required or permitted to be taken at a meeting of the stockholders may be taken without a meeting if, before or after the action, a written consent thereto is signed by stockholders holding at least a majority of the voting power, except that if a different proportion of voting power is required for such an action at a meeting, then that proportion of written consents is required. The Southern Mineral bylaws provide that any action, except election of directors, which may be taken by the vote of the stockholders at a meeting, may be taken without a meeting if authorized by the written consent of stockholders holding at least a majority of the voting power, unless the provisions of the statutes or of the articles of incorporation require a greater proportion of voting power to authorize such action in which case such greater proportion of written consents shall be required. Approval by Shareholders of a Merger, Share Exchange or Sale of All Assets Under Texas law, a plan of merger, a share exchange, or a sale of all or substantially all of the assets of a corporation not in the regular course of business requires shareholder approval by at least a two-thirds vote of the outstanding shares entitled to vote on the matter, unless the articles of incorporation require a lesser number. However, unless the articles of incorporation provide otherwise, shareholder approval is not required in a merger where . the corporation is the sole surviving corporation in the merger; . the articles of incorporation will not differ from the articles of incorporation before the merger; . each shareholder of the corporation whose shares were outstanding immediately before the merger will hold the same number of shares with identical rights after the merger; . the voting power of the number of voting shares outstanding immediately after the merger, plus the voting power of the Under Nevada law, generally a plan of merger or exchange must be recommended by the board of directors and approved by a majority of the voting power unless the articles of incorporation or the board of directors require a greater vote. Written notice stating the purpose, or one of the purposes, of the meeting is to consider the plan, together with a copy or a summary of the plan, shall be given to each shareholder of record, whether or not such shareholder is entitled to vote at the meeting, within the time and in the manner for the giving of notice of meetings of shareholders. Nevada law also provides dissenters' rights as further described under "Dissenters' Rights" on page 37. 73 PetroCorp Southern Mineral --------- ---------------- number of voting shares that the corporation will issue as a result of the merger, if any, does not exceed 20% of the voting power of the total number of voting shares outstanding immediately before the merger; . the number of participating shares, plus the number of participating shares issued as a result of the merger, will not exceed by more than 20% the total number of participating shares of the corporation outstanding immediately before the merger; and . the board of directors adopts a resolution approving the plan of merger; or . where the merger is of a corporation with or into a direct or indirect wholly owned subsidiary of the corporation and after the merger the corporation or its successor is a direct or indirect wholly owned subsidiary of a holding company and other requirements are met. Texas law provides that a shareholder shall have the right to dissent to any merger where shareholder approval was required and the shareholder was entitled to vote on the merger. A shareholder shall have the right to dissent to a plan of exchange where the shareholder's shares are to be acquired, or to a merger if the shareholder was entitled to vote on the matter. However, under certain conditions, the shareholder shall not have a right to dissent to a merger where there is a single surviving or new corporation, nor to a share exchange. Neither the PetroCorp articles of incorporation nor the Southern Mineral articles of incorporation vary their respective state laws regarding the above. Because Southern Mineral is merging into PetroCorp Acquisition, and not PetroCorp, Texas law does not require approval by two-thirds of PetroCorp's shareholders. The rules of the AMEX, on which PetroCorp's stock is listed, require the transaction be approved by a majority of the PetroCorp shares represented (in person or by proxy) at a meeting at which a quorum exists. 74 PetroCorp Southern Mineral --------- ---------------- Business Combinations Under Texas law, certain business combinations between public corporations and affiliated shareholders (or any affiliate or associate of the affiliated shareholder) are prohibited during the three year period immediately following the affiliated shareholders share acquisition unless two-thirds of the unaffiliated shareholders approve the transaction at a meeting held no earlier than six months after the shareholder acquires the shares. Such a vote of the shareholders is not required for business combinations where . the board of directors of the issuing public corporation approves the business combination or the acquisition of shares by the affiliated shareholder prior to the affiliated shareholder becoming an affiliated shareholder; . the affiliated shareholder was affiliated before December 31, 1996 and continued as such through the transaction; . the affiliated shareholder became affiliated through transfer of shares by will or intestate succession; . the affiliated shareholder became affiliated inadvertently and subsequently divests itself of shares; . the issuing public corporation combines with a domestic wholly owned subsidiary, if the domestic subsidiary is not an affiliate or associate of the affiliated shareholder other than by reason of the affiliated shareholder's beneficial ownership of voting shares in the issuing public corporation; or . the issuing public corporation's articles of incorporation elect not to be governed by this particular Texas statute. An affiliated shareholder is a person other than the issuing public corporation or its subsidiary that beneficially owns 20% or more of the outstanding voting shares of the issuing public corporation, or within the preceding three years was such an owner. Sections 78.411 to 78.444 of the Nevada Revised Statutes restrict the ability of a Nevada corporation having at least 200 stockholders of record to engage in any "combination" with an "interested stockholder" for three years after the interested stockholder's date of acquiring the shares that cause the stockholder to become an interested stockholder, unless the combination or the purchase of shares by the interested stockholder is approved by the board of directors before that date. The statute also puts certain restrictions on such combinations after the three year period expires. An "interested stockholder" means the beneficial owner of 10% or more of the voting power of the corporation and certain affiliates and associates of the corporation. For purposes of this computation various attribution rules will deem a person to be the owner of stock considered under the statute to be under that person's control even though not actually owned by that person. A "combination" is broadly defined to include almost all, if not all, but relatively minor transactions. A merger would be considered a combination. The Southern Mineral articles of incorporation also include an election to be governed by the business combination statute. The Nevada business combination statute is not applicable to the merger. 75 PetroCorp Southern Mineral --------- ---------------- Although PetroCorp's articles of incorporation do not provide for exemption from the Texas business combination voting requirements, PetroCorp was not an affiliate of Southern Mineral or any affiliate or associate of Southern Mineral that owned a material amount of Southern Mineral Stock. Accordingly, the Texas Business Combination Statute is not applicable to the merger. Indemnification of Directors and Officers Under the Texas law, a corporation may indemnify a director against judgments, penalties (including excise and similar taxes), fines, settlements and reasonable expenses actually incurred in connection with a proceeding, if it is determined by the requisite vote of directors or shareholders or by legal counsel that the person: . conducted himself in good faith; . reasonably believed, in the case of official conduct as a director, that his conduct was in the corporation's best interests, and, in all other cases, that his conduct was not opposed to the corporation's best interests; and . in the case of any criminal proceeding, had no reasonable cause to believe his conduct was unlawful. . A director may not be indemnified in respect of a proceeding in which the person is found liable on the basis that personal benefit was improperly received by him or in which the person is found liable to the corporation, except that indemnification may be provided if it is limited to reasonable expenses actually incurred by the person in connection with the proceeding and shall not be made in respect to any proceeding in which the person is found liable for willful or intentional misconduct in the performance of his duty to the corporation. . Under the Texas law, a corporation must indemnify a director or officer against reasonable expenses incurred by him in connection with a proceeding in which he is a named defendant or respondent because he is or was a director if he has Nevada law provides that a corporation may indemnify any person who was, or is, or is threatened to be made a party in a completed, pending, or threatened proceeding, whether civil, criminal, administrative, or investigative (except an action by or in the right of the corporation), by reason of being or having been an officer, director, employee, or agent of the corporation or serving in certain capacities at the request of the corporation. Indemnification may include attorney's fees, judgments, fines and amounts paid in settlement. The person to be indemnified must have acted in good faith and in a manner he or she reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action, such person must have had no reasonable cause to believe his or her conduct was unlawful. With respect to actions by or in the right of the corporation, indemnification may not be made for any claim, issue, or matter as to which such a person has been finally adjudged by a court of competent jurisdiction to be liable to the corporation or for amounts paid in settlement to the corporation, unless and only to the extent that the court in which the action was brought or other court of competent jurisdiction determines upon application that in view of all circumstances the person is fairly and reasonably entitled to indemnity for such expenses as the court deems proper. Unless indemnification is ordered by a court in an action by or in the right of the corporation, the indemnification determination must be made by the stockholders, by a majority vote of a quorum of the board of directors who were not parties to the action, suit or proceeding, or in certain circumstances by independent legal counsel in a written opinion. The articles of incorporation, bylaws, or an agreement made by the corporation 76 PetroCorp Southern Mineral --------- ---------------- been wholly successful in the defense of the proceeding. Under certain circumstances a corporation may pay or reimburse a director for reasonable expenses incurred in advance of the final disposition of the proceeding. . A corporation may also indemnify and advance expenses to any officer, employee, agent or certain other persons serving at the request of the corporation to the extent permitted by law, the articles of incorporation, bylaws, action of directors or contract. . A corporation may purchase insurance on behalf of such persons against any liability asserted against him and incurred in or arising out of such person's capacity with respect to the corporation. The PetroCorp bylaws provide that PetroCorp must indemnify its directors and officers from and against any and all liabilities, costs and expenses incurred by them in such capacities to the fullest extent permitted by the Texas law and that PetroCorp has the power to purchase and maintain liability insurance for such persons as permitted by the Texas law. may, however, provide for payment to an officer or director of the expenses of defending an action as incurred and in advance of final disposition upon receipt of an undertaking to repay the amount if it is ultimately determined by a court of competent jurisdiction that the person is not entitled to indemnification. Nevada law also provides that to the extent a director, officer, employee, or agent has been successful on the merits or otherwise in the defense of any action, he or she must be indemnified by the corporation against expenses, including attorneys' fees, actually and reasonably incurred in connection with the defense. Indemnification, unless ordered by a court in an action by or in the right of the corporation or for advancement of expenses subject to an undertaking to repay the amount if it is ultimately determined by a court of competent jurisdiction that the person is not entitled to indemnification, may not be made to or on behalf of any director or officer if a final adjudication establishes that his or her acts or omissions involved intentional misconduct, fraud, or a knowing violation of the law and was material to the cause of action. The Southern Mineral bylaws provide that Southern Mineral must indemnify its directors and officers from and against any and all liabilities, costs and expenses incurred by them in such capacities to the fullest extent permitted by the Nevada law and that Southern Mineral has the power to purchase and maintain liability insurance for such persons as permitted by the Nevada law. 77 PetroCorp Southern Mineral --------- ---------------- Limitation of Liability of Directors and Officers Texas law permits a corporation to include in its articles of incorporation a provision that a director of the corporation is not liable to the corporation or its shareholders for monetary damages for an act or omission in the director's capacity as a director, except that such a provision cannot eliminate or limit the liability of a director for: . a breach of a director's duty of loyalty to the corporation or its shareholders; . an act or omission not in good faith that constitutes a breach of duty of the director to the corporation or an act or omission that involves intentional misconduct or a knowing violation of the law; . a transaction from which a director received an improper benefit, whether or not the benefit resulted from an action taken within the scope of the director's office; or . an act or omission for which the liability of a director is expressly provided for by statute. A director who votes for or assents to a distribution that is not permitted by statute and who did not use ordinary care or good faith reliance on appropriate information to make the decision is jointly and severally liable to the corporation for the amount by which the distributed amount exceeds the amount permitted by statute; however, if the distribution would have been permitted by statute on any date after the date of the vote or assent, the director shall have no liability. Under Texas law, an officer is not liable for discharging any duty or power in good faith and with ordinary care in reliance on reports, opinions, information or statements prepared or presented by other officers or employees of the corporation, including members of the board of directors; or legal counsel, accountants or other persons believed to have expertise in the matter. The PetroCorp and Southern Mineral articles both contain provisions which eliminate director liability to the fullest extent provided by law. Nevada law provides that the articles of incorporation may contain a provision which limits the liability of directors or officers to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer. The limitation of liability does not apply to acts or omissions which involved intentional misconduct, fraud, a knowing violation of law, or payment of a dividend in violation of Nevada law. Such provision limits recourse for money damages which might otherwise be available to the corporation or its shareholders for certain acts or omissions in breach of fiduciary duty by individuals while acting as officers or directors. Although this provision would not prohibit injunctive or similar actions against directors or officers, the practical effect of such relief would be limited. 78 PetroCorp Southern Mineral --------- ---------------- Shareholder Rights Plan On November 12, 1998, the PetroCorp board of directors adopted a shareholder rights plan. Under the plan, each shareholder of record at the close of business on November 23, 1998 received one Series A Preferred Stock Purchase Right for each share of common stock held. Approximately 8,656,019 million rights were distributed. The rights expire on November 12, 2008. Each right entitles the shareholder to purchase 1/1000 of a preferred share for a purchase price of $24.00. Each such fraction of a preferred share has terms designed to make it essentially equivalent to one share of common stock. The rights will become exercisable only in the event a person or group acquires 55% or more of PetroCorp's common stock or commences a tender or exchange offer which, if consummated, would result in that person or group owning 55% of the common stock. Prior to such an event, the rights are evidenced by and traded in tandem with the common stock. If a person or group acquires a 55% or larger position in PetroCorp, each right (except those held by the acquiring party) will then entitle its holder to purchase, at a price of $24, fractional shares of preferred stock having a value equal $48, or twice the purchase price, with each fractional preferred share valued at the market price of common stock. The effect will be to entitle the holder to buy PetroCorp common stock at 50% of the market price. Also, if following an acquisition of 55% or more of PetroCorp's common stock, PetroCorp is acquired by that person or group in a merger or other business combination transaction, each right would entitle its holder to purchase common stock of the acquiring company having a value of twice the purchase price. The effect will be to entitle the PetroCorp shareholder to buy stock in the acquiring company at 50% of its market price. PetroCorp may redeem the rights at $.001 per right at any time on or prior to the tenth business day following the acquisition of 55% or more of its common stock by a person or group or commencement of a tender offer for such 55% ownership. Southern Mineral does not have any shareholder rights plans. 79 THE SHAREHOLDER MEETINGS Information about the Shareholder Meetings and Voting The PetroCorp and Southern Mineral boards are using this document to solicit proxies from their shareholders for use at the special meetings. Time and Place of the Shareholder Meetings PetroCorp: Southern Mineral: 1:00 p.m., local time 9:00 a.m., local time Tulsa Room, 9th Floor The Doubletree Hotel Bank of Oklahoma Tower 400 Dallas Street One Williams Center Houston, Texas 77002 Tulsa, Oklahoma 74172 Proposals PetroCorp shareholders will vote on a proposal to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock in connection with the merger. Southern Mineral shareholders will vote on a proposal to approve the merger agreement and the transactions contemplated by the merger agreement, including the merger. Record Date for the Special Meetings You may vote at your shareholders' meeting if you owned shares of PetroCorp or Southern Mineral common stock at the close of business on March 26, 2001. Outstanding Shares Held on Record Date On the record date, 8,721,819 shares of PetroCorp common stock, and 12,261,460 shares of Southern Mineral common stock were outstanding. Shares Entitled to Vote at the Meetings For each share of common stock that you own on that date, you will have one vote on each proposal to be presented at the meeting. Shares of common stock deemed beneficially held by PetroCorp or Southern Mineral or their subsidiaries will not be voted. Quorum Requirement for the Meetings The presence at the meeting, in person or by proxy, of the holders of a majority of the outstanding shares of common stock is necessary to constitute a quorum. If a quorum is not represented at the meeting, a vote for adjournment will be taken among the shareholders present or represented by proxy vote for adjournment. Abstentions and broker non-votes count as present for establishing a quorum. Shares of common stock held by PetroCorp or Southern Mineral or their subsidiaries do not count towards a quorum. A "broker non-vote" occurs with respect to a proposal when a broker is not permitted to vote on that proposal without instruction from the beneficial owner of the shares of common stock and no instruction is given. 80 Shares Beneficially Owned By PetroCorp and Southern Mineral Directors and Executive Officers As Of Record Date Executive officers and directors of PetroCorp collectively own 4,601,938 shares of PetroCorp common stock. Executive officers and directors of Southern Mineral collectively own 2,651,025 shares of Southern Mineral common stock. These shares represent approximately 54.4% of the shares of PetroCorp common stock outstanding as of record date and 21.6% of Southern Mineral shares as of record date. These individuals are not a party to a shareholder agreement, with the exception of Messrs. Coughlin, Wiese and Fuller, but they have indicated that they intend to vote their outstanding shares of common stock in favor of the proposals. Votes Necessary at the Meetings to Approve PetroCorp and Southern Mineral Proposals Approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger, requires the approval of the holders of a majority of the outstanding shares of Southern Mineral common stock entitled to vote on the merger. Three directors, Messrs. Fuller, Coughlin and Wiese, solely in their capacity as shareholders of Southern Mineral, are parties to shareholder agreements pursuant to which they have agreed to vote their shares of Southern Mineral common stock in favor of the merger, representing approximately 18.3% of the shares of Southern Mineral common stock outstanding as of the record date for voting at the special meeting. Approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock requires approval by the holders of a majority of all outstanding shares of PetroCorp common stock present, in person or by proxy, at a meeting at which a quorum is present. Two large shareholders are parties to shareholder agreements pursuant to which they have agreed to vote their shares of PetroCorp common stock in favor of the merger, representing approximately 69.6% of the shares of PetroCorp common stock outstanding as of the record date. Voting By Proxy You may vote in person at your meeting or by proxy. We recommend you vote by proxy even if you plan to attend your meeting. You can always revoke your proxy by changing your vote prior to or at your meeting. You may vote by proxy by completing, signing, dating and returning the card in the enclosed envelope. The members of the PetroCorp board of directors unanimously approved and recommend that you vote for approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger and the issuance of PetroCorp common stock in connection with the merger. The members of the Southern Mineral board of directors, each of which is an independent director, unanimously approved and recommend that you vote for approval of the merger agreement and the transactions contemplated by the merger agreement, including the merger. Approval by Southern Mineral and PetroCorp shareholders of the merger agreement and the transactions contemplated by the merger agreement, are conditions to consummation of the merger. 81 Revoking Your Proxy You may revoke your proxy before it is voted by: . submitting a new proxy with a later date, . notifying your company's Secretary in writing before your shareholder's Meeting that you have revoked your proxy; or . voting in person, or notifying the Secretary orally of your wish to revoke your proxy, at your shareholder's meeting. Other Voting Matters Voting in Person. If you plan to attend your meeting and wish to vote in person, we will give you a ballot at your meeting. However, if your shares of common stock are held in the name of a brokerage firm or trustee, you must obtain from the firm or trustee an account statement, letter or other evidence of your beneficial ownership of the common shares. People with Disabilities. We can provide reasonable assistance to help you participate in your shareholder's meeting if you tell us about your disability and your plan to attend. Please call or write the Secretary of your company at least two weeks before your shareholder's meeting at the number or address provided on page . Proxy Solicitation. We will each pay our own costs of soliciting proxies, including the reasonable expenses of brokers, banks, fiduciaries and other nominees in forwarding solicitation material to beneficial owners. In addition to the solicitation of proxies by use of the mail, solicitation may be made by telephone and facsimile and PetroCorp and Southern Mineral may utilize the services of some of their respective officers and employees to solicit proxies personally. Such officers and employees will not be additionally compensated for such solicitation, but may be reimbursed for out-of-pocket expenses incurred in connection therewith. If undertaken, we expect the expense of such solicitation by officers and employees to be nominal. Both parties will file with the SEC all materials used to aid in the solicitation of proxies. You should submit your proxy without delay by mail. Also will reimburse brokers and other nominees for their expenses in sending these materials to you and getting your voting instructions. Do not send in any Southern Mineral stock certificates with your proxy cards. If the conditions to the merger, including the condition that Southern Mineral shareholders submit stock election forms covering at least 3,000,000 shares of PetroCorp stock, are satisfied or waived, the exchange agent will mail transmittal forms with instructions for the surrender of stock certificates promptly after the closing of the merger. Other Business; Adjournments and Postponements We currently are not aware of any other business to be acted upon at either meeting. If, however, other matters are properly brought before either meeting, or any adjourned or postponed meeting, your proxies will have discretion to vote or act on those matters according to their best judgment, including to adjourn the meeting. Adjournments or postponements of the shareholder meetings may be made for the purpose of, among other things, soliciting additional proxies. Any adjournment may be made from time to time by approval of the holders of common shares representing a majority of the votes present in person or by proxy at the meeting, whether or not a quorum exists, without further notice other than by an announcement made at the special meeting. A vote by proxy against the merger will result in such proxy being voted against an adjournment or postponement of the shareholder meeting to solicit additional proxies. A vote by proxy in favor of the merger will result in such proxy being voted for an adjournment or postponement of a shareholder meeting to solicit additional proxies. 82 THE COMPANIES Southern Mineral Overview and History Southern Mineral is an independent oil and gas company headquartered in Houston, Texas, and engaged in the acquisition, exploitation, exploration and operation of oil and gas properties, primarily along the Gulf Coast of the United States, in Canada and in Ecuador. Southern Mineral was incorporated in 1937 as a vehicle to consolidate mineral tracts retained as its parent company lumbered large tracts of southern Mississippi forestlands. For the next 50 years, Southern Mineral was largely a passive participant in the oil and gas business, merely granting leases on its spread of mineral interests in Mississippi. In the mid-1980s, Southern Mineral became a more active participant in the oil and gas business, redeploying its significant cash flow from revenues derived from the Poplarville Field in southern Mississippi into exploration activities. For the next ten years, Southern Mineral pursued the sole strategy of exploration for oil and gas. As a result of generally poor results, Southern Mineral changed its focus beginning in 1995 to one of a more balanced program of acquisitions, exploitation and exploration. Southern Mineral completed a series of acquisitions over the next few years, including, among others, the following: . Diverse GP III. In April 1995, Southern Mineral acquired Diverse Production Co., subsequently named SMC Production Co., whose primary asset was a 18.906% general partnership interest in Diverse GP III. At the time of the acquisition, Diverse GP III owned interests in over four hundred oil and gas properties located in eleven states. As a result of the acquisition, Southern Mineral's proven reserves more than doubled from its January 1, 1995, reported reserves. . Big Escambia Creek, Alabama. During 1997 and 1998, Southern Mineral acquired working interests in the Big Escambia Creek Field and the surrounding area in a series of six transactions. The largest acquisition was the purchase of BEC Energy in May 1997, for $10.6 million. Thereafter, Southern Mineral acquired additional working interests in the area for $12.1 million. The Big Escambia Creek Field represents Southern Mineral's largest asset in terms of reserves with approximately 2.2 million barrels of oil equivalent proved reserves as of December 31, 1999. In addition to sales of oil and gas, Southern Mineral earned $779,000 in revenues during 1999 from the sale of sulfur from the field. . Amerac Energy. In January 1998, Southern Mineral issued 3,333,333 shares for all the outstanding shares of Amerac Energy. At January 1, 1998, Amerac had proved reserves of 32.7 billion cubic feet of gas equivalent. Subsequent to the acquisition, Southern Mineral sold a number of non- strategic Amerac properties, and the remainder became a part of Southern Mineral's U.S. oil and gas asset base. . Neutrino Resources. In July 1998, Southern Mineral acquired, for cash, all of the outstanding shares of Neutrino Resources, an independent oil and gas company located in Calgary, Canada, for a total purchase price of $57,198,000, including assumption of debt and working capital deficit. Following the acquisition, Southern Mineral consolidated its other Canadian assets into Neutrino, and began to operate in Canada exclusively through Neutrino. Neutrino's principal assets at December 31, 1999 were in the Pine Creek Field and the Inverness/Swan Hills Field in central and southern Alberta, Canada. At year-end 1999, Neutrino's proved reserves totaled 3.9 million barrels of liquids (oil, condensate and natural gas liquids) and 18.8 billion cubic feet of natural gas. In 1999, Southern Mineral's Canadian production was approximately 494,000 barrels of liquids and 2,300 million cubic feet of natural gas. In March 2000, Neutrino sold its interests in Inverness and Swan Hills in Alberta, Canada, for $9.0 million. Southern Mineral endured poor operating results in 1998 and its financial condition at the end of 1998 resulted in Southern Mineral's independent auditors, in their opinion on the 1998 financial statements, 83 disclosing their substantial doubt about Southern Mineral's ability to continue as a going concern. In February 1999, the Southern Mineral board retained CIBC World Markets Corp. as independent advisors to assist in evaluating various strategic alternatives for maximizing shareholder value. On July 21, 1999, Southern Mineral announced that its board had approved a restructuring of Southern Mineral that involved a $20.6 million equity infusion, the sale of the Brushy Creek and Texan Garden Fields in Texas and an exchange offer for its 6.875% Convertible Subordinated Debentures due 2007. However, based upon discussions with certain of the holders of its debentures, the Southern Mineral board concluded that the restructuring could not be consummated on the terms previously contemplated. On October 29, 1999, Southern Mineral and its wholly-owned subsidiaries (other than Neutrino) filed voluntary petitions for relief under Chapter 11, Title 11 of the United States Code, in order to facilitate the restructuring of Southern Mineral's long-term debt, revolving credit, trade debt and other obligations. The filings were made in the U.S. Bankruptcy Court for the Southern District of Texas, Victoria Division. All debts of Southern Mineral, except those of Neutrino Resources, Inc., as of October 29, 1999 were stayed by the bankruptcy petitions, and were subject to compromise pursuant to such proceedings. Southern Mineral decided to seek protection because it concluded that a restructuring of its indebtedness could not be completed without the protection and assistance of the bankruptcy court. The timing of the bankruptcy filing was imposed by several factors, including the possible acceleration of Southern Mineral's $16.1 million of indebtedness by its domestic bank creditors and the inability of Southern Mineral to reach a satisfactory compromise with its debenture holders regarding the consideration to be received in a previously proposed restructuring. The bankruptcy petitions were filed in order to preserve cash and to give Southern Mineral the opportunity to restructure its debt. Southern Mineral operated as a debtor-in-possession subject to the bankruptcy court's supervision and orders. Southern Mineral emerged from bankruptcy on August 1, 2000. The terms of the reorganization called for the holders of Southern Mineral's debentures to exchange the debentures for 78% of the common equity of Southern Mineral with the remaining 22% to go to prior equity owners of Southern Mineral. In the reorganization, $41.4 million worth of debentures and $1.6 million of accrued interest was satisfied in exchange for 9,536,422 shares of Southern Mineral common stock. Prior to the reorganization Southern Mineral had 2,608,760 shares outstanding; subsequent to the reorganization Southern Mineral had 12,145,182 shares outstanding. Shareholders, option holders and warrant holders of record on July 24, 2000, received approximately 3,667,000 Series B perpetual warrants allowing them to increase their ownership from 22% to up to 40% of the outstanding common stock. Southern Mineral's board of directors was restructured with five of seven new members appointed by the creditors' committee or by large former debenture holders. Corporate Overview The following table shows Southern Mineral's principal subsidiaries and equity investments, including their domicile and our percentage ownership in each: Percentage Entity Domicile Ownership ------ -------- ---------- BEC Energy............................................... Texas 100% SMC Ecuador.............................................. Delaware 100% SMC Production........................................... Texas 100% Neutrino Resources....................................... Alberta 100% Spruce Hills Production.................................. Delaware 100% 84 Canadian Operations Approximately 37% of Southern Mineral's oil and gas revenues during the year ended December 31, 2000 were derived from Canadian properties. The costs and revenues associated with Southern Mineral's Canadian operations are denominated in Canadian dollars. Southern Mineral prepares its consolidated financial statements in U.S. dollars. Fluctuations in the value of the two currencies may cause currency translation losses for Southern Mineral or reduced revenues and earnings, or both, with respect to its Canadian operations. Southern Mineral cannot predict the effect of exchange rate fluctuations upon future operating results. Neutrino's principal assets at December 31, 2000 include one core area in the Pine Creek Field in central and southern Alberta, Canada. At year-end 2000, Neutrino's proved reserves totaled 2.0 million barrels of liquids (oil, condensate and natural gas liquids) and 15.5 billion cubic feet of natural gas. In 2000, Southern Mineral's Canadian production was approximately 308,000 barrels of liquids and 1,555 million cubic feet of natural gas. On March 1, 2000, Southern Mineral sold its interests in the Inverness/Swan Hills Field for approximately $9.0 million resulting in a loss of $5.3 million, which was recorded in Southern Mineral's financial statements as an impairment charge at December 31, 1999. Customers We usually sell our oil and gas in the spot market or on such other bases that may be impacted by the effect of changes in current market prices.

The oil and gas reserves are principally onshore in the continental United States, Canada and Ecuador. Southern Mineral's reserve information has been based on estimates prepared by or audited by independent petroleum engineers. Netherland, Sewell & Associates, Inc. prepared the domestic and Ecuador reserve estimates. Chapman Petroleum Engineering Ltd. prepared most of the Canadian reserve estimates, while Gilbert Laustsen Jung Associates Ltd. prepared the remaining Canadian reserves estimates as of such dates. Southern Mineral's U.S. oil reserves (including oil, condensate and natural gas liquids) have been prepared using year-end oil prices received by Southern Mineral of $25.52 per barrel and gas reserves were prepared using year-end prices received by Southern Mineral of $10.05 per thousand cubic feet (Mcf). The Canadian reserves have been prepared using year-end oil prices received by Southern Mineral of $26.42 per barrel and year-end natural gas prices of $9.38 per Mcf. Ecuador reserves were prepared using a year-end oil price of $28.53. See "Risk Factors -- Reserve estimates depend on many assumptions that may not turn out to be accurate. Any material inaccuracies in these reserve estimates or underlying assumptions will materially affect the quantities and net present value of our reserves" on page 22, "Management's Discussion and Analysis of Financial Condition and Results of Operations" beginning on page 90 and "Notes to the Consolidated Financial Statements" beginning on page F-13.

Competition There is a high degree of competition in the oil and gas exploration and production industry. Consequently, Southern Mineral competes with many other entities for capital and desirable potential acquisitions and exploration and development prospects. Southern Mineral's competitors include the major integrated oil companies, as well as numerous independent oil and gas companies and other producers of energy sources and fuels. Many of these competitors have capital resources much greater than that of Southern Mineral, and may therefore be better able than Southern Mineral to withstand and compete during adverse market conditions. Southern Mineral's ability to generate revenues and reserves in the future will be dependent upon, among other things, its success in competing with these competitors. Southern Mineral's geographic diversity of operations in Canada and the Gulf of Mexico provides Southern Mineral with an advantage with respect to its competition. 88 Regulations Domestic Environmental Regulation. Southern Mineral's operations are subject to numerous federal, state, and local laws and regulations relating to environmental protection. These laws and regulations may require the acquisition of permits before drilling commences; restrict or prohibit the types, quantities and concentration of substances that can be released into the environment in connection with drilling and production activities; prohibit drilling activities on certain lands lying within wetlands or other protected areas, impose restrictions on the injection of liquid into subsurface formations, require remedial measures to mitigate pollution from former operations (such as pit closure and plugging abandoned wells), and impose substantial liabilities for pollution resulting from drilling and production operations. Moreover, state and federal environmental laws and regulations may become more stringent, and public interest in the protection of the environment has increased dramatically in recent years. While we do not anticipate that Southern Mineral will be required in the near future to spend amounts that are material in relation to our total capital expenditure program due to environmental laws and regulations, because such laws and regulations are frequently changed, we are unable to predict with certainty the ultimate cost of compliance. Southern Mineral generates wastes that may be subject to the federal Resource Conservation and Recovery Act of 1976, as amended, or the RCRA, and comparable state statutes. The U.S. Environmental Protection Agency and various state agencies have limited the approved methods of disposal for certain hazardous and non-hazardous wastes. Moreover, legislation has been proposed in Congress from time to time that would amend the RCRA to reclassify oil and gas production wastes as "hazardous waste." If such legislation were enacted, it could have a significant impact on the Company's operating costs, as well as on the oil and gas industry in general. Southern Mineral currently owns or leases numerous properties that for many years have been used for the exploration and production of oil and gas. Although Southern Mineral believes that it has used good operating and waste disposal practices, prior owners and operators of these properties may not have used similar practices, and hydrocarbons or other wastes may have been disposed of or released on or under Southern Mineral's properties or on or under locations where such wastes have been taken for disposal. In addition, many of these properties have been operated by third parties whose treatment and disposal or release of hydrocarbons or other wastes was not under Southern Mineral's control. The properties and the wastes disposed thereon may be subject to the Comprehensive Environmental Response, Compensation and Liability Act of 1980, as amended, or CERCLA, RCRA and analogous state laws as well as state laws governing the management of oil and gas wastes. Under such laws, Southern Mineral could be required to remove or remediate previously disposed wastes (including wastes disposed or released by prior owners or operators) or property contamination (including groundwater contamination), or to perform remedial plugging operations to prevent future contamination. The Oil Pollution Act, or OPA, contains numerous requirements relating to the prevention of and response to oil spills into waters of the United States. The OPA subjects persons responsible for "offshore facilities" to strict joint and several liability for all containment and cleanup costs and certain other damages arising from a spill, including, but not limited to, the costs of responding to a release of oil to surface waters. OPA also requires owners and operators of offshore facilities that could be the source of an oil spill into federal or state waters, including wetlands, to post a bond, letter of credit or other form of financial assurance in amounts ranging from $10 million in specified state waters to $35 million in federal outer continental shelf waters to cover costs that could be incurred by governmental authorities in responding to an oil spill. Such financial assurances may be increased by as much as $150 million if a formal risk assessment indicates that the increase is warranted. Noncompliance with OPA would subject Southern Mineral to varying civil and criminal penalties and liabilities. OPA imposes a variety of additional requirements on "responsible parties" for vessels or oil and gas facilities related to the prevention of oil spills and liability for damages resulting from such spills in waters of the United States. The "responsible party" includes the owner or operator of an onshore facility, pipeline, or vessel or the lessee or permittee of the area in which an offshore facility is located. OPA assigns liability to 89 each responsible party for oil spill removal costs and a variety of public and private damages from oil spills. While liability limits apply in some circumstances, a party cannot take advantage of liability limits if the spill is caused by gross negligence or willful misconduct or resulted from violation of a federal safety, construction or operating regulation. If a party fails to report a spill or to cooperate fully in the cleanup, liability limits likewise do not apply. OPA establishes a liability limit for offshore facilities (including pipelines) of all removal costs plus $75 million. Few defenses exist to the liability for oil spills imposed by OPA. OPA also imposes other requirements on facility operators, such as the preparation of an oil spill contingency plan. Failure to comply with ongoing requirements or inadequate cooperation in a spill event may subject a responsible party to civil or criminal enforcement actions. The Federal Water Pollution Control Act, as amended, commonly known as the Clean Water Act or CWA, and comparable state laws and regulations require certain owners or operators of facilities that store or otherwise handle oil, such as Southern Mineral, to prepare and implement spill prevention, control, countermeasure and response plans relating to the possible discharge of oil into surface waters. The CWA also imposes restrictions and strict controls regarding the discharge of produced waters and other oil and gas wastes into navigable waters. Under the CWA, permits must be obtained to discharge pollutants into state and federal waters. The CWA and analogous state laws provide for civil, criminal and administrative penalties for any unauthorized discharges of oil and other hazardous substances in reportable quantities and, along with the OPA, may impose substantial potential liability for the costs of removal, remediation and damages. State water discharge regulations and the federal permits prohibit, or severely restrict the discharge of, produced water and sand, and some other substances related to the oil and gas industry, to coastal waters. Although the costs to comply with zero discharge mandates under federal or state law may be significant, the entire oil and gas industry has experienced or is experiencing similar costs. Southern Mineral believes that these costs will not have a material adverse impact on its financial condition and results of operations. Some oil and gas exploration and production facilities are also required to obtain permits for their storm water discharges. Costs may be incurred in connection with treatment of wastewater or developing storm water pollution prevention plans. Our operations may be subject to the Clean Air Act and comparable state and local requirements. Amendments to the CAA were adopted in 1990 and contain provisions that may result in the gradual imposition of certain pollution control requirements with respect to air emissions from Southern Mineral's operations. The EPA and various states have been developing regulations to implement these requirements. Southern Mineral may be required to incur certain capital expenditures in the next several years for air pollution control equipment in connection with maintaining or obtaining operating permits and approvals addressing other air emission-related issues. However, Southern Mineral does not believe its operations will be materially affected by any such requirements. International Environmental Regulation. Southern Mineral's operations in Canada and Ecuador are subject to numerous federal, provincial and local laws and regulations. Environmental legislation provides for restrictions and prohibitions on releases or emissions of various substances produced in association with certain oil and gas industry operations and can affect the location and operation of wells and other facilities and the extent to which exploration and development is permitted. In Canada, legislation also requires that well and facility sites be abandoned and reclaimed to the satisfaction of provincial authorities and local landowners. A breach of such legislation may result in the suspension or revocation of licenses and authorizations, and the suspension of operations, as well as the imposition of clean-up orders, fines and penalties. In addition, certain types of operations may require environmental assessment and reviews to be completed before approvals are obtained and before exploration or development projects are begun. Southern Mineral does not anticipate that it will be required to make capital or other expenditures by reason of international environmental laws and regulations that are material in relation to its total capital expenditure program or that would have a material adverse effect on its earnings, but inasmuch as such laws and regulations, are frequently changed, Southern Mineral is unable to predict the ultimate cost of compliance. Domestic Oil and Gas Regulation. Complex regulations concerning all phases of energy development at the local, state and federal levels apply to Southern Mineral's operations and often require interpretation by 90 Southern Mineral's professional staff or outside advisors. The federal government and various state governments have adopted numerous laws and regulations respecting the production, transportation, marketing and sale of oil and natural gas. Regulation by state and local governments usually covers matters such as the spacing of wells, allowable production rates, environmental protection, pollution control, taxation and other related matters. Moreover, future changes in local, state or federal laws and regulations could adversely affect Southern Mineral's operations. Domestic exploration for, and production of, oil and gas are extensively regulated at both the federal and state levels. Legislation affecting the oil and gas industry is under constant review for amendment or expansion, frequently increasing the regulatory burden. Numerous departments and agencies, both federal and state, are also authorized by statute to issue, and have issued, rules and regulations binding on the oil and gas industry that often are costly to comply with and that carry substantial penalties for non- compliance. In addition, production operations are affected by changing tax and other laws relating to the petroleum industry, by constantly changing administrative regulations, and possible interruption or termination by government authorities. As a producer and seller of natural gas, Southern Mineral depends on transportation and storage services offered by various interstate and intrastate pipeline companies for the delivery and sale of its gas supplies. Transportation and storage services rendered by interstate natural gas pipelines are subject to the jurisdiction of the Federal Energy Regulatory Commission, or the FERC, under the Natural Gas Act of 1938 and the Natural Gas Policy Act of 1978. Competition across the natural gas industry has intensified in recent years as a result of certain major rulemakings promulgated by the FERC requiring interstate natural gas pipelines to unbundle transportation and sales services and to render open-access transportation service on a nondiscriminatory basis for third-party gas supplies. These FERC initiatives have resulted in interstate pipelines abandoning their traditional merchant function and offering various types and levels of services to their customers, which, in turn, has greatly enhanced the ability of producers and others to market natural gas supplies to local distribution companies and large commercial and industrial end users. The rates charged for interstate natural gas pipeline services are often subject to negotiation between customers and the pipeline within certain FERC- approved parameters. These rates are subject to change depending upon individual system usage and other variables. Additionally, the availability of interstate transportation and storage service necessary for Southern Mineral to make sales or deliveries of gas can at times be preempted by other users of a particular pipeline system in accordance with FERC-approved methods for allocating open-access pipeline capacity. The regulations affecting interstate pipeline services are subject to ongoing review and amendment. Within the past year, FERC has issued several notices of proposed rulemakings and inquiry through which it has indicated that it is considering modifying certain existing regulations and policies in an effort to . maximize competition in short-term transportation markets, . provide interstate pipelines with additional flexibility in order to better tailor rates and terms and conditions of service to individual customer needs, and . better fashion regulatory policies that provide the correct incentives and price signals for all segments of the industry while continuing to guard against the exercise of market power. While these and other potential FERC-initiatives may further facilitate market access for natural gas producers, they will also likely result in increased competition in markets in which the Company's natural gas is sold which could negatively affect revenues in the future. As a producer and seller of oil, Southern Mineral depends on services offered by various interstate and intrastate oil pipelines. Services provided by intrastate oil pipelines are subject to the jurisdiction of individual state regulatory commissions, and the rules and regulations of these individual commissions are subject to ongoing review and possible amendment. The rates, terms and conditions of service and certain other aspects of 91 interstate oil pipeline service are subject to regulation under the Interstate Commerce Act, which is administered by the FERC. Canadian Oil and Gas Regulation. The oil and natural gas industry in Canada is subject to extensive legislation and regulation governing its operations including land tenure, exploration, development, production, refining, transportation, marketing, environmental protection, exports, taxes, labor standards and health and safety standards imposed by legislation enacted by various levels of government. In addition, extensive legislation and regulation exists with respect to pricing and taxation of oil and natural gas and related products. Employees At March 7, 2001, Southern Mineral employed 16 full-time persons and 11 consultants. Southern Mineral is not subject to a collective bargaining agreement and believes that its relations with its employees and consultants are good. Legal Proceedings Southern Mineral is involved in several lawsuits arising in the ordinary course of business. Management believes that the outcome of such proceedings will not have a material adverse effect in the aggregate on Southern Mineral's financial position or results of operations. Management's Discussion and Analysis of Financial Condition and Results of Operations In addition to the above discussion, the following is intended to assist you in understanding our financial condition and results of operations for each of the years ended December 31, 2000, 1999 and 1998. This discussion should be read together with the selected consolidated financial data and the consolidated financial statements and related footnotes included in this document. The following information contains forward-looking statements based on our current expectations, assumptions, estimates and projections about us and our industry which involve risks and uncertainties. Accounting Policies We use the successful efforts method of accounting for oil and gas property acquisition, exploration, development, and production activities. Property acquisition, exploration well and development well costs are capitalized as incurred. Unsuccessful exploration well costs are subsequently charged to exploration expense. Other exploration costs, including geological and geophysical costs, the costs of retaining unproved property and costs to operate and maintain wells and equipment are expensed as incurred. Capitalized costs are amortized by field using the units-of-production method. Acquisition costs are amortized based on proved reserves. Development costs are amortized based on proved developed reserves. Capitalized costs of unproved properties are excluded from amortization until such time as proved reserves are established or impairment is determined. External Factors Our results of operations and the period to period comparability of our financial results are affected by external factors, including changes in the price of crude oil. Oil prices have historically been highly volatile. See "Risk Factors--Risks Related to PetroCorp after the Merger." Results of operations for the year ended December 31, 2000 as compared to the year ended December 31, 1999 Oil and gas revenues for the year ended December 31, 2000 were $33,581,000 compared to oil and gas revenues of $25,865,000 for the same period in 1999. Oil and natural gas liquids, or NGL, production 92 decreased 19% to 695,308 barrels and natural gas production decreased 25% to 4,046 million cubic feet, or mmcf, in the year ended December 31, 2000 compared to the year ended December 31, 1999. The lower production levels in the year ended December 31, 2000 are due primarily to the sale of properties in 1999 and the first quarter of 2000 and natural declines in producing properties. Increases in commodity prices more than offset the impact of the lower volumes. Southern Mineral's average realized oil and NGL price increased 70% from $15.39 per barrel in the year ended December 31, 1999 to $26.15 in the year ended December 31, 2000. Southern Mineral's average realized natural gas prices increased 73% to $3.60 per thousand cubic feet during the year ended December 31, 2000 compared to $2.08 per thousand cubic feet in the same period a year earlier. During the first quarter of 1999, Southern Mineral sold its mineral interests and substantially all of its royalty interests in Texas, New Mexico and Mississippi for approximately $6,000,000. The gain on the sale of these assets was $5,073,000. The proceeds from asset sales in the first quarter of 1999 were used to reduce bank indebtedness and for other corporate purposes. During the third quarter of 1999, Southern Mineral sold domestic properties resulting in a net gain of approximately $7.1 million with no significant sales in 2000. For the year ended December 31, 2000, production costs, including production and ad valorem taxes, decreased 2% to $8,730,000 compared to $8,898,000 in the year ended December 31, 1999. However, on an energy equivalent unit basis, production costs rose 26%, resulting primarily from non-recurring workovers and other operations Exploration, dry hole and lease impairment expenses incurred in the year ended December 31, 2000 were $511,000, compared to $2,501,000 in the same period in 1999. The 1999 expense is primarily from impairments of a portion of the property held for sale and non-producing properties. Since Southern Mineral uses the successful efforts method of accounting, exploration expenses may vary greatly from period to period based upon the level of exploration activity. General and administrative expenses were $3,248,000 in the year ended December 31, 2000, a 17% decrease from $3,926,000 in the prior year's period primarily related to reductions in force through attrition and layoffs in 1999 offset by charges related to issuance of common shares to Southern Mineral's new directors in lieu of cash compensation and application of FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation, or FIN 144. On an energy equivalent unit basis, costs increased 6% from the year ended December 31, 1999 to the same period in 2000. Depreciation, depletion and amortization, or DD&A, decreased 32% to $8,306,000 in the year ended December 31, 2000 compared to $12,302,000 in 1999 primarily related to decrease in production due to property sales. On a unit of equivalent production basis, DD&A decreased 14% from $1.15 per thousand cubic feet equivalent to $0.99 per thousand cubic feet equivalent. Restructuring and bankruptcy costs were $5,544,000 in the year ended December 31, 2000 compared to $4,388,000 in 1999. The costs for 2000 relate primarily to charges associated with Southern Mineral's plan of reorganization, which became effective August 1, 2000 and application of FIN 44. The 1999 costs relate to charges associated with the proposed restructuring as filed with the Securities and Exchange Commission on July 21, 1999, which was not consummated. Interest and debt expense in the year ended December 31, 2000 was $2,470,000 compared to $6,236,000 in the same period in 1999. The decrease primarily reflects the reduced indebtedness outstanding due to the application of proceeds from property sales to debt reduction and no accrual of interest related to subordinated debt in accordance with Statement of Position 90-7, Financial Reporting by Entities in Reorganization Under the Bankruptcy Code, or SOP 90-7, through the effective date of the plan of reorganization. Tax provision in the year ended December 31, 2000 was $2,415,000 compared to tax benefit of $2,882,000 in the same period in 1999. The increase in tax provision primarily reflects increased pre-tax income from 93 Company's Canadian operations in the year ended December 31, 2000 compared to a loss in the same period in 1999, state income tax liability associated with Southern Mineral's U.S. operations in 2000 and change in Southern Mineral's tax strategy for its Canadian operations subsequent to December 31, 1999. The extraordinary gain occurred in the third quarter of 2000 resulting from the exchange of Southern Mineral's debentures for shares of common stock based on the closing price of Southern Mineral's common stock on the plan of reorganization confirmation date. Southern Mineral recorded net income of $10,854,000, or $1.62 per basic share for the year ended December 31, 2000 compared to a net loss of $5,758,000 or $2.25 per basic share for the year ended December 31, 1999. Results of operations for the year ended December 31, 1999 as compared to the year ended December 31, 1998 Oil and gas revenues for 1999, were $25,865,000, up 19% compared to oil and gas revenues for the same period in 1998 of $21,722,000. The increase in revenues reflects higher production volumes of crude oil and natural gas liquids and increased natural gas and crude oil prices. The higher production volumes are primarily the result of the inclusion of Neutrino for an entire year in 1999 compared to six months of 1998 offset by decreased production related to properties sold during 1999. Natural gas production for 1999 was 5,395 million cubic feet, a 16% decrease as compared to production for the same period in 1998 of 6,433 million cubic feet. Southern Mineral's crude oil and natural gas liquids production for 1999 increased 13% to 856,407 barrels as compared to 756,552 barrels for the same period in 1998. Production levels for 1999, when compared to 1998, reflect increased production from Neutrino beginning in July 1998, offset by decreased production related to property sales from Neutrino in the fourth quarter of 1998, the domestic mineral and royalty interests in the first quarter of 1999 and the Brushy Creek and Texan Gardens Field in the third quarter of 1999. Average realized natural gas prices for 1999 increased 10% to $2.08 per thousand cubic feet compared to $1.89 per thousand cubic feet in the same period of 1998. During 1999, crude oil prices increased 35% to $15.39 per barrel, compared to $11.36 per barrel in the same period in 1998. Gain on sale of properties in 1999 was $11,976,000 compared to a loss of $250,000 in 1998. The 1999 gain is primarily the result of sales of mineral interests in the first quarter and Brushy Creek and Texan Garden Fields in the third quarter of 1999. Production costs, including production and ad valorem taxes, increased in 1999 to $8,898,000, up 4% from $8,518,000 in the same period in 1998, due in part to the acquisition of Neutrino, which occurred in July 1998. On a cost per thousand cubic feet equivalent basis, production costs in 1999 increased to $0.84 per thousand cubic feet equivalent, or up 8% from $0.78 per thousand cubic feet equivalent in 1998. Exploration, dry hole and lease impairment expenses decreased for 1999 to $2,501,000, compared to $3,635,000 in the same period of 1998. The 1999 expense is primarily from impairments of properties held for sale and non-producing properties. The amount recorded for 1998 was due primarily to a dry hole drilled in Lafourche Parish, Louisiana in which Southern Mineral had a 93% working interest. Since Southern Mineral uses the successful efforts method of accounting, exploration expenses may vary greatly from period to period based upon the level of exploration activity. Depreciation, depletion and amortization expense for 1999 increased to $12,302,000, up 17% from $10,505,000 in 1998. Southern Mineral computes depreciation and depletion on each producing property using the unit-of- production method. Since this method employs estimates of remaining reserves, depreciation and depletion expenses may vary from period to period because of revisions to reserve estimates, production rates and other factors. Depreciation, depletion and amortization expense increased in 1999 to $1.15 per thousand 94 cubic feet equivalent, up 20% from $0.96 per thousand cubic feet equivalent in 1998. The increase reflects inclusion of Neutrino beginning in July 1998 at a higher per unit average depletion cost and the sales of primarily natural gas properties of Neutrino in the fourth quarter of 1998, the domestic mineral and royalty interests in the first quarter of 1999 and the Brushy Creek Field in the third quarter of 1999, all with lower per unit average depletion costs. General and administrative expenses increased to $3,926,000 in 1999, up 8% from $3,622,000 in 1998. However, on a cost per thousand cubic feet equivalent basis, general and administrative expenses increased 12% for 1999 to $0.37 per thousand cubic feet equivalent from $0.33 per thousand cubic feet equivalent in the same period of 1998. The increase in general and administrative expenses for 1999, when compared to 1998, is not as great as would have been expected due to the full year effect of Neutrino. Significant reductions in work force through attrition and layoffs have occurred in 1999. In 1998 Southern Mineral accrued and paid bonuses of $360,000 with no corresponding amounts in 1999. Impairment of proved oil and gas properties decreased to $8,686,000, down 7% compared to $9,344,000 in 1998. The 1999 impairments were primarily $3,386,000 to reflect revision of previous estimates and $5,300,000 to adjust Neutrino's cost basis in Inverness and Swan Hills Fields to their net realized value based on the estimated sales price received in 2000. Significant declines in world oil prices during 1998 resulted in a writedown in the book value of a number of proved oil and gas properties during the fourth quarter of 1998. Restructuring and bankruptcy costs were $4,388,000 in 1999 compared to no such costs in 1998. The Southern Mineral board concluded that the proposed restructuring plan as filed with the SEC on July 21, 1999 could not be consummated on the terms contemplated. Therefore, the estimated costs associated with the restructuring of approximately $1,372,000 were expensed during the third and fourth quarters of 1999. Since Southern Mineral's filing for bankruptcy on October 29, 1999, it has incurred approximately $553,000 related to the bankruptcy. In addition $2,463,000 capitalized as other assets for fees and expenses related to securing the domestic bank debt and convertible subordinated debentures were expensed during the fourth quarter of 1999 pursuant to Statement of Position 90-7 "Financial Reporting by Entities in Reorganization Under the Bankruptcy Code." Interest and debt expense in 1999 was $6,236,000, compared to $5,362,000 in the same period in 1998. Interest expense increased as a result of an increase in the outstanding bank debt incurred and assumed with Neutrino in July 1998 and because of increased rates of interest charged by Southern Mineral's domestic and Canadian banks. Subsequent to the filing of bankruptcy, no additional interest was accrued in accordance with Statement of Position 90-7. The additional interest from October 29, 1999 to December 31, 1999 would have been $474,375. Tax benefits in 1999 and 1998 were $2,882,000 and $2,775,000, respectively, resulting from pre-tax loss from Southern Mineral's Canadian operations. As a result of the above items, Southern Mineral reported a net loss in 1999 of $5,758,000 or $2.25 per basic share, compared to a loss of $16,409,000, or $6.60 per basic share in 1998. Liquidity and Capital Resources Southern Mineral has historically funded its operations, acquisitions, exploration and development expenditures from cash flows from operating activities, bank borrowing, issuance of common stock and debt securities, and the sale of assets. Southern Minerals's cash flow provided by operating activities for the year ended December 31, 2000 was $14,144,000, for the year ended December 31, 1999 was $3,396,000, and for the year ended December 31, 1998 was $6,670,000. Additional cash from the sale of assets was received in the amount of $9,142,000 in 2000, $26,119,000 in 1999 and $11,508,000 in 1998. 95 On October 29, 1999, Southern Mineral and its wholly-owned subsidiaries (other than Neutrino) filed voluntary petitions for relief under Chapter 11, Title 11 of the United States Code, in order to facilitate the restructuring of Southern Mineral's long-term debt, revolving credit, trade debt and other obligations. The filings were made in the U.S. Bankruptcy Court for the Southern District of Texas, Victoria Division. Southern Mineral emerged from bankruptcy on August 1, 2000. All debts of Southern Mineral, except those of Neutrino, as of October 29, 1999 were stayed by the bankruptcy petitions, and were subject to compromise pursuant to such proceedings until August 1, 2000. Southern Mineral operated as a debtor-in-possession subject to the bankruptcy court's supervision and orders. Southern Mineral decided to seek protection because it concluded that a restructuring of its indebtedness could not be completed without the protection and assistance of the bankruptcy court. The timing of the bankruptcy filing was imposed by several factors, including the possible acceleration of Southern Mineral's $16.1 million of indebtedness by its domestic bank creditors and the inability of Southern Mineral to reach a satisfactory compromise with its debenture holders regarding the consideration to be received in a previously proposed restructuring. The bankruptcy petitions were filed in order to preserve cash and to give Southern Mineral the opportunity to restructure its debt. In the ordinary course of business, Southern Mineral makes substantial capital expenditures for the acquisitions, exploration and development of oil and natural gas reserves. Historically, Southern Mineral has financed its capital expenditures, debt service and working capital requirements with cash flow from operations, public offerings of equity, private offerings of debt, asset sales, borrowings under its senior credit facility and other financings. Cash flow from operations is sensitive to the prices Southern Mineral receives for its oil and natural gas production. Lower hydrocarbon production associated with a reduction in planned capital spending or an extended decline in oil and gas prices could result in less than anticipated cash flow from operations in later years, which could have a material adverse effect on Southern Mineral. On August 23, 2000, Southern Mineral entered into a new credit facility with BankOne Texas in the principal amount of up to $30,000,000. At December 31, 2000, this domestic credit facility provides for a borrowing base of $17,625,000 and matures on August 23, 2003. The borrowing base reduces $275,000 per month. We used proceeds from the domestic credit facility to repay the prior domestic facility as provided in Southern Mineral's final plan of reorganization. The obligations under the domestic credit facility are secured by substantially all of the assets, other than Neutrino's assets. The domestic credit facility prohibits the payment of dividends and contains covenants relating to Southern Mineral's financial condition, including the following: . Southern Mineral must maintain at all times no less than a 1 to 1 ratio of current assets to current liabilities; . Southern Mineral's tangible net worth as of the close of any fiscal quarter must be equal to or greater than 85% of Southern Mineral's tangible net worth on September 1, 2000 plus 75% of Southern Mineral's positive quarterly net income and 100% of any new equity; and . Southern Mineral's ratio as of the close of any fiscal quarter of its EBITDA, or earnings before interest, taxes, and depreciation and amortization expense, to payments of principal and interest on its debt must exceed 1.2 to 1. Southern Mineral is in compliance as of the most recent applicable date with the covenants relating to financial condition in its domestic credit facility. At December 31, 2000, the outstanding borrowing was $14,282,512. On March 7, 2001 outstanding borrowings under the domestic credit facility were $13,582,512 with borrowing availability of $3,767,488. Outstanding principal under the domestic credit facility bears interest at the index rate published by BankOne Texas plus 0.5% (10.0% at December 31, 2000) to the extent of the borrowing base utilized. The borrowing base is redetermined semi-annually in May and November at the sole discretion of the domestic lender. Southern Mineral may request four additional borrowing base redeterminations during any calendar year except that no more than one redetermination will be made each calendar quarter. On August 29, 2000, Neutrino repaid its prior Canadian credit facility and entered into a new loan facility in the principal amount of up to U.S. $30,000,000 loan facility with BankOne Canada. At December 31, 2000 96 the borrowing base under the Canadian credit facility is U.S. $10,075,000 and is due August 29, 2003. At December 31, 2000, outstanding borrowings under the Canadian credit facility were U.S. $2,531,814. The Canadian credit facility is secured by substantially all of Neutrino's assets and guaranteed by Southern Mineral. On March 7, 2001, outstanding borrowings under the Canadian credit facility were U.S. $1,950,000 (Canadian $3,000,000) with a borrowing available of U.S. $7,940,000 (Canadian $12,215,384). Outstanding principal under the Canadian credit facility bears interest at BankOne Canada prime rate plus 0.5% (8.0% at December 31, 2000) to the extent of the borrowing base utilized. The Canadian credit facility contains certain covenants relating to the financial condition of Neutrino, including the following: . Neutrino must maintain at all times no less than a 1 to 1 ratio of current assets to current liabilities; . Neutrino's tangible net worth as of the close of any fiscal quarter must be equal to or greater than 85% of Neutrino's tangible net worth on August 31, 2000 plus 75% of Neutrino's positive quarterly net income and 100% of any new equity; and . Neutrino's ratio as of the close of any fiscal quarter of its EBITDA, or earnings before interest, taxes, and depreciation and amortization expense, to payments of principal and interest on its debt must exceed 1.2 to 1. Neutrino is in compliance as of the most recent applicable date with the covenants relating to financial condition in its credit facility. The borrowing base under the Canadian credit facility is subject to semi-annual redeterminations beginning November 2000. The borrowing base is redetermined semi-annually beginning November 2000 and will be made at the sole discretion of the Canadian lender. Neutrino may request four additional borrowing base redeterminations during any calendar year except that no more than one redetermination will be made each calendar quarter. The outstanding balance under the old Canadian credit facility was classified as a current liability because of the demand feature of the loan. However, it was management's intention that the facility be utilized to provide long-term financing for Southern Mineral. The domestic credit facility would require the consent of BankOne Texas, and the Canadian facility would require the consent of BankOne Canada, to remain outstanding following the merger. However, PetroCorp has agreed under the merger agreement to fully pay off such credit facilities upon the closing of the merger. Southern Mineral did not declare dividends in the years ended December 31, 2000 and 1999. Southern Mineral does not expect, under its existing capital structure, to be able to pay dividends for the foreseeable future. Payment of dividends is currently prohibited by the terms of Southern Mineral's domestic credit facility. Quantitative and Qualitative Disclosures about Market Risk Southern Mineral is exposed to a variety of market risks including the potential for adverse changes in oil and gas natural gas prices, foreign currency exchange rates and interest rates. Southern Mineral's revenue stream is significantly affected by the level of oil and natural gas prices, which can be volatile and over which Southern Mineral has no control or influence. Southern Mineral has utilized natural gas and oil price swaps and collars on a limited basis to hedge a portion of its exposure to commodity price fluctuations. The effect of price swaps is to fix the price for a specific quantity of gas or oil for a specific time and collars are to secure a maximum and minimum price for a specific time. During 1998 and 1999, the Company entered into natural gas and oil price swaps and collars with third parties to hedge a portion of its production from the effects of fluctuations in the market price of natural gas and oil. Due to the bankruptcy filing, all third-party oil and gas hedges were cancelled by the counter-parties to these contracts, resulting in the Company's recognition of a loss of approximately $163,000 during 1999. 97 Subsequent to the Company's emergence from bankruptcy and as required by the Company's Domestic and Canadian Credit Facilities, the Company has entered into the following crude oil and natural gas costless collars in 2000.

The fair value at December 31, 2000 of collars was a net unrealized loss of $3.1 million. Southern Mineral operates in Canada and Ecuador, as well as the United States and, as a result, is exposed to some foreign exchange rate risk. Natural gas prices in Canada and oil prices in Canada and Ecuador tend to respond to changes in the value of the local currencies versus the U.S. dollar. The Company believes the economic exposure to it from fluctuations in currency exchange rates is not material to its financial condition, results from operations or cash flows. Southern Mineral has two primary sources of debt financing: its domestic bank credit facility and its Canadian bank credit facility. In Canada, Southern Mineral has utilized interest rate swaps as a means of fixing the interest rate on its indebtedness. The following table presents Southern Mineral's indebtedness at December 31, 2000 as it relates to interest rate type and maturity. Given the amount of Southern Mineral's variable rate indebtedness at December 31, 2000, and taking into account the interest rate swap currently in place, a 10% change in interest rates would imply an annualized change in pre- tax interest expense of approximately $32,000. 2001 2002 2003 Thereafter Total Fair Value ----- -------- ---------- ---------- ----------- ----------- Variable Rate Domestic Bank Debt.... -- $ 14,282,512 -- $14,282,512 $14,282,512 Canadian Bank Debt.... -- -- 2,531,814 -- 2,531,814 2,531,814 ----- -------- ---------- ----- ----------- ----------- -- $ 16,814,326 -- $16,814,326 $16,814,326 Average Rate........ 9.7% 9.70% 98 In August 2000, Southern Mineral fixed the rate of interest on its outstanding bank borrowings under its Canadian credit facility through interest rate swaps. At December 31, 2000, the fair value of Southern Mineral's interest rate swap was a loss of approximately $94,000. Recent Accounting Pronouncements Effective January 1, 2001, Southern Mineral adopted Statement of Financial Accounting Standards No. 133, or SFAS 133, Accounting for Derivative Instruments and Hedging Activities, and SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, an amendment of FASB Statement No. 133. These statements establish accounting and reporting standards requiring that derivative instruments, including certain derivative instruments embedded in other contracts, be recorded on the balance sheet at fair value as either assets or liabilities. The accounting for change in the fair value of a derivative instrument depends on the intended use and designation of the derivative at its inception. Special accounting for qualifying hedges allows a derivative's gains and losses to offset related results of the hedged item in the statement of operations, and requires Southern Mineral to formally document, designate and assess the effectiveness of the hedge transaction to receive hedge accounting. For derivatives designated as cash flow hedges, changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Overall hedge effectiveness is measured at least quarterly. Any changes in the fair value of the derivative instrument resulting from hedge ineffectiveness, as defined by SFAS 133 and measured based on the cumulative changes in the fair value of the derivative instrument and the cumulative changes in the estimated future cash flows of the hedged item, are recognized immediately in earnings. Southern Mineral has designated all of its commodity hedges as cash flow hedges. Adoption of SFAS 133, resulted in the recognition of $197,000 of derivative assets and $3.4 million of derivative liabilities on the Company balance sheet and $1.9 million, net of taxes, of hedging losses included in accumulated other comprehensive income as the cumulative effect of a change in accounting principle and $796,000, net of taxes, recorded as a cumulative effect of change in accounting principle to net income. Amounts are determined as of January 1, 2001 based on market quotes and portfolio of derivative instruments. PetroCorp PetroCorp is an independent oil and gas company engaged in the acquisition, exploration, and development of oil and gas properties in North America. PetroCorp's activities are conducted principally in the states of Oklahoma, Texas, Mississippi, Louisiana and Kansas, and in the province of Alberta, Canada. As of December 31, 2000, PetroCorp had estimated proved reserves of approximately 75 billion cubic feet of natural gas and 4.2 million barrels of oil. PetroCorp had an estimated pretax present value of future net revenues, discounted at 10%, of $410 million as of December 31, 2000. On a thousand cubic feet equivalent basis, approximately 75% of PetroCorp's proved reserves were natural gas at such date. In addition, PetroCorp has unproved properties with a net book value of $2 million, as well as interests in natural gas processing and gathering facilities with a net book value of $3 million. PetroCorp's business strategy is to acquire, explore and develop oil and natural gas properties in North America. PetroCorp has grown, in large part, through the acquisition of producing oil and gas properties. PetroCorp generally focuses on acquisitions of long-lived natural gas reserves located onshore in North America and prefers acquisitions that provide additional potential through development or exploitation efforts, as well as exploratory drilling opportunities. Exploration and development activities are also an important component of PetroCorp's business strategy. Through its management agreement with Kaiser-Francis, PetroCorp expects to be able to allocate a greater portion of future cash flows to exploration and development activities. PetroCorp was formed in July 1983 as a Delaware corporation and in December 1986 contributed its assets to a newly formed Texas general partnership. In October 1992, PetroCorp changed its legal form from a 99 Texas general partnership to a Texas corporation. In August 1999, PetroCorp signed a management agreement with its largest shareholder, Kaiser-Francis. At that time, Gary Christopher was named president and chief executive officer of PetroCorp. Mr. Christopher is an employee of Kaiser-Francis and has served on PetroCorp's board since 1996. PetroCorp's principal executive offices are located at 6733 South Yale Avenue, Tulsa, Oklahoma 74136, with a mailing address of P.O. Box 21298, Tulsa, Oklahoma 74121-1298, and its telephone number is (918) 491-4500. Pursuant to SEC rules, PetroCorp, unlike Southern Mineral, may incorporate certain documents by reference. In addition to the information provided below you should also refer to the documents incorporated by reference by PetroCorp described on page 101 "Where You Can Find More Information," as well as PetroCorp's Amended 2000 Annual Report on Form 10-K, attached as Annex XI. Financing the Transaction PetroCorp plans to finance the merger through existing lines of credit. Receipt of financing is not a condition to the merger. PetroCorp's Management Agreement with Kaiser-Francis In connection with the purchase by Kaiser-Francis of PetroCorp common stock from two significant shareholders during 1996, Kaiser-Francis succeeded to rights under a registration rights agreement previously entered into between PetroCorp and those shareholders, which agreement is substantially similar to another registration rights agreement previously entered into between PetroCorp and two subsidiaries of St. Paul. As part of a restructuring plan, on August 3, 1999, PetroCorp's board entered into the Kaiser-Francis management agreement, under which Kaiser- Francis provides management, technical, and administrative support services for all of PetroCorp's operations in the United States and Canada. The shareholders of PetroCorp approved the management agreement in October 1999 and it took effect on November 1, 1999. A new slate of corporate officers was approved at that time. The management agreement provides that Kaiser-Francis will perform oil and gas operations and administrative support functions with respect to PetroCorp's properties in both the United States and Canada. Oil and gas operations to be performed by Kaiser-Francis include, for example: . geological and geophysical functions, including prospect generation and evaluation; . identification and evaluation of potential property acquisitions and divestitures; . engineering; . lease operations; . marketing; . contract negotiation and administration; . regulatory compliance; and . land functions. In addition, Kaiser-Francis performs administrative functions on behalf of PetroCorp, including, for example: . land functions; . accounting, tax and audit functions; 100 . insurance; . investor relations; and . retaining third party consultants, such as attorneys and accountants, on behalf of PetroCorp. Under the management agreement, Kaiser-Francis may not make material decisions without the approval of Petrocorp's Board of Directors. Material decisions include: . expenditures in excess of $250,000; . sales of PetroCorp assets valued in excess of $500,000; . long term production sales agreements; . placement of certain liens on the Company's assets; and . initiation or settlement of material litigation. PetroCorp's principal officers, who will be approved by PetroCorp's Board of Directors, will be responsible for executing all contracts and other instruments on behalf of the Company. For properties not operated by PetroCorp, the services fee payable to Kaiser-Francis is, in most cases, equal to $50.00 per month per well. As to properties operated by PetroCorp, Kaiser-Francis receives as its services fee the administrative and overhead fees charged under applicable operating agreements. In addition, PetroCorp pays Kaiser-Francis a monthly service fee of $12,500. For services of a non-routine nature that are performed in-house by Kaiser- Francis, Kaiser-Francis shall receive compensation at a mutually agreed rate that is competitive with the generally available rate charged for such services. PetroCorp also reimburses Kaiser-Francis for certain direct out-of- pocket expenses identified in the management agreement that are incurred by Kaiser-Francis in performing its obligations thereunder. PetroCorp estimates that the aggregate services fee, including the operations of Southern Mineral, will equal approximately $2,300,000 per year at the companies' respective current levels of operation. For the year ended December 31, 2000, Kaiser- Francis received $1,419,000 from PetroCorp for management fees under the management agreement. 101 SOUTHERN MINERAL WARRANT HOLDERS In accordance with the terms of Southern Mineral's warrants, PetroCorp will assume all obligations under any Southern Mineral warrants outstanding after the merger closes and each holder of any such warrants will have the right to receive the per share merger consideration she would have received for each share of Southern Mineral stock she would have owned if she had exercised such warrant immediately before the merger. Accordingly, for each hypothetical share of Southern Mineral underlying the warrants, such warrant holder will receive the per share merger consideration in cash, without interest, upon exercise of the warrant and payment of the warrant exercise amount. Stock election forms will be mailed to warrant holders at the same time they are mailed to shareholders. A holder of a warrant that . receives a stock election form, . exercises her warrant in accordance with the applicable warrant agreement after receipt of a stock election form but prior to the expiration of the stock election period, and . otherwise delivers a stock election form with respect to the shares issuable under her warrant, will have made a valid stock election with respect to shares issuable under her warrant only if the warrants are exercised on or prior to the expiration of the stock election period so that she is the record holder of the shares at the expiration of the stock election period. Any Southern Mineral Series B Perpetual Warrant may be exercised in whole or part, at any time or from time to time, by . surrendering the warrant certificate to the warrant agent with a duly executed subscription form from the warrant certificate, and . paying in full the warrant price of $4.21 per full share of Southern Mineral common stock and any applicable taxes, as provided in the Southern Mineral Series B Perpetual Warrant Agreement, a copy of which is attached as Annex X. The warrant agent is America Stock Transfer & Trust Company, 6201 Fifteenth Avenue New York, New York, 11219. PetroCorp does not plan on maintaining a market for the Southern Mineral warrants should the merger be consummated.

F-13 F-1 PETROCORP INCORPORATED UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS The following presents the unaudited pro forma combined financial statements after giving effect to the acquisition by PetroCorp of Southern Mineral. The unaudited pro forma balance sheet is based on the historical balance sheets of PetroCorp incorporated by reference herein, and Southern Mineral appearing elsewhere in this document and has been prepared to reflect the acquisition by PetroCorp of Southern Mineral as if the acquisition had occurred on December 31, 2000. The unaudited pro forma statement of operations is based on the historical statement of operations of PetroCorp incorporated by reference herein, and the historical statement of operations of Southern Mineral appearing elsewhere in this document, and reflects the results of operations of PetroCorp and of Southern Mineral for the year ended December 31, 2000, as if the acquisition occurred on January 1, 2000. These unaudited pro forma statements should be read in conjunction with the historical financial statements and notes thereto of PetroCorp and Southern Mineral included elsewhere in this document. The unaudited pro forma combined financial statements do not purport to be indicative of the results of operations that would actually have occurred if the transaction described had occurred as presented in such statements or that may occur in the future. As described in "Risks Related to PetroCorp After the Merger" on page 19, PetroCorp is managed by Kaiser-Francis under a Management Agreement. The terms of the Management Agreement are described on pages 96 and 97. In addition, future results may vary significantly from the results reflected in such statements due to general economic conditions, oil and gas commodity prices, PetroCorp's ability to successfully integrate the operations of Southern Mineral with its current business and several other factors, many of which are beyond PetroCorp's control. See "Risk Factors" beginning on page 23. The Southern Mineral acquisition will be accounted for using the purchase method. After the acquisition, the purchase cost will be allocated to the PetroCorp assets and liabilities based on the respective fair values at the date the merger was agreed to and announced. The final allocation of the actual purchase price is subject to the final valuation of the acquired assets and assumed liabilities, but that allocation is not expected to differ materially from the preliminary allocation presented in these pro forma combined financial statement. This final allocation is expected to occur as soon as all relevant data for evaluating property values can be obtained. In no case will this evaluation go beyond December 31, 2001. As described in Note A to the Unaudited Pro Forma Combined Financial Statements and elsewhere in this document, PetroCorp will issue from a minimum of 3,000,000 to a maximum of 4,108,968 shares of PetroCorp stock, based on the elections of Southern Mineral shareholders and warrant and option holders. Southern Mineral shareholders and warrant and option holders who do not receive stock will receive a right to receive cash of $4.71 per share, net of any warrant or option exercise price, for each share, option or warrant held.

The fair value of PetroCorp common stock used in the pro forma calculations is $9.75 per share, which reflects the trading price three days prior and three days after the date on which the merger was agreed to and announced. Warrant and option holders who do not exercise prior to the consummation of the merger will receive a right to cash equal to the net of $4.71 less the exercise price. For purposes of these pro forma financial statements, it is assumed that all warrants and options are exercised at December 31, 2000, and therefore the net purchase consideration related to warrant and option holders reflected in the purchase price allocation is $1,834,000 and $246,000, respectively. The pro forma data based on 3,000,000 shares being issued show an additional cash outlay of $11,089,000. This results in a purchase price that is $277,000 higher (additional allocation to property, plant and equipment of $356,000, less $79,000 of additional deferred income taxes) than the pro forma data based on 4,108,968 shares being issued.

The fair value of current liabilities includes the following estimated incremental costs to be borne by Southern Mineral: $1,357,000 for severance and retention payments, $1,240,000 for investment advisory fees and $350,000 for legal, accounting, printing and filing costs related to the merger agreement, which will be incurred by Southern Mineral. (These adjustments are not included in the unaudited pro forma combined statement of operations, however they are included in the combined balance sheet.) B Record estimated drawdown of additional long-term debt to complete financing of transaction. The pro forma data based on 3 million shares being issued include additional borrowings of $10 million in order to complete the transaction. C Adjust Southern Mineral's exploration expense and gain (loss) of sale of properties which are shown as current items of profit and loss under the successful efforts method of accounting, but are adjustments to property, plant and equipment under the full cost method of accounting for oil and gas producing activities which is used by PetroCorp. D Record depreciation, depletion and amortization expense of oil and gas properties using a rate of $.82 per thousand cubic feet equivalent (Mcfe) based on combined production of 19,011,000 Mcfe for the year ended December 31, 2000 and combined reserves of 198,774,000 Mcfe at January 1, 2000. This combined rate reflects the impact of the allocation of purchase price to Southern Mineral's proved oil and gas properties. Included in total depreciation, depletion and amortization expense is $1,524,000 related to non-oil and gas properties. For 2000, PetroCorp and Southern Mineral, respectively, had composite oil and gas depreciation, depletion and amortization rates of $.74 and $1.15 per Mcfe. E Record deferred income tax effects of the pro forma adjustments at a statutory rate of 38%. F Record interest expense on net debt required to consummate the merger transaction, based on interest rates currently in effect of 7.9%. Each 1/8 percent increase in interest rates would result in $12,500 of additional interest expense. G To record $175,000 for legal, accounting, printing and filing costs associated with the registration of PetroCorp common stock. H To reclassify sulfur revenue to conform to PetroCorp's presentation. F-6 INDEPENDENT AUDITORS' REPORT The Board of Directors Southern Mineral Corporation: We have audited the accompanying consolidated balance sheets of Southern Mineral Corporation and subsidiaries as of December 31, 2000 and 1999, and the related consolidated statements of operations, stockholders' equity and comprehensive income (loss), and cash flows for each of the years in the three- year period ended December 31, 2000. These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of Southern Mineral Corporation and subsidiaries as of December 31, 2000 and 1999, and the consolidated results of their operations and their cash flows for each of the years in the three-year period ended December 31, 2000, in conformity with accounting principles generally accepted in the United States of America.

F-12 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS General Business--Southern Mineral Corporation, a Nevada corporation, with its subsidiaries ("Southern Mineral" or the "Company"), is an independent oil and gas company headquartered in Houston, Texas. The Company is engaged in the acquisition, exploitation, exploration and operation of oil and gas properties, primarily along the Gulf Coast of the United States, in Canada and in Ecuador. The Company conducts its operations in Canada exclusively through its subsidiary, Neutrino Resources Inc. ("Neutrino"). The Company's business strategy is to increase reserves and shareholder value through a balanced program of acquisitions, exploitation and exploration. On October 29, 1999 ("Petition Date"), the Company and its wholly-owned subsidiaries, BEC Energy, Inc., Amerac Energy Corporation, SMC Ecuador, Inc. and SMC Production Company ("Debtor Subsidiaries"), filed voluntary petitions for relief under Chapter 11, Title 11 of the United States Code ("Bankruptcy Code"), in order to facilitate the restructuring of the Company's long-term debt, revolving credit, trade debt and other obligations. The filings were made in the U.S. Bankruptcy Court for the Southern District of Texas, Victoria Division ("Bankruptcy Court"). The Company and its Debtor Subsidiaries emerged from Bankruptcy on August 1, 2000 ("Effective Date"). The Company and its Debtor Subsidiaries operated as debtors-in-possession subject to the Bankruptcy Court's supervision and orders until the Effective Date. See Note 2 for further information. Note 1. Summary of Significant Accounting Policies Basis of Presentation--Beginning in the fourth quarter of 1999, and for the year ended December 31, 1999, the consolidated financial statements of the Company and its subsidiaries are presented in accordance with Statement of Position 90-7 "Financial Reporting by Entities in Reorganization Under the Bankruptcy Code" (SOP 90-7). SOP 90-7 provides guidance on financial reporting by entities that have filed petitions with the bankruptcy court and expect to reorganize as going concerns under Chapter 11 of title 11 of the United States Code. SOP 90-7 generally requires the reclassification of the consolidated balance sheet, statement of operations and cash flows to distinguish transactions and events that are directly associated with the reorganization from the ongoing operations of the Company. As discussed above, the Company filed for reorganization under Chapter 11 of the United States Bankruptcy Code. Subsequent to emergence from Chapter 11 in 2000, the Company has presented its financial statements in accordance with generally accepted accounting principles in a manner consistent with prior periods. Principles of Consolidation--The consolidated financial statements include the accounts of Southern Mineral Corporation and its wholly owned subsidiaries. In consolidation, all significant intercompany transactions have been eliminated. The Company accounts for its investment in oil and gas partnerships and joint ventures using the proportional consolidation method. Revenues--Natural gas revenues generally are recorded using the sales method, whereby the Company recognizes natural gas revenue based on the amount of gas sold to purchasers on its behalf. All other revenue is also recorded using the sales method. The Company believes that imbalances related to the sales of natural gas are insignificant. Foreign Currency Translation--Translation adjustments result from the process of translating foreign subsidiaries' financial statements into U.S. dollars in circumstances where the subsidiaries functional currency is not the U.S. dollar. The Canadian dollar is the functional currency for the Company's Canadian subsidiaries as substantially all transactions are conducted in the local currency. The U. S. dollar is considered the functional currency for the Company's Ecuadorian operations, as predominately all transactions in these operations are denominated in U. S. dollars. Balance sheet accounts are translated at exchange rates in effect at the balance sheet date. Income statement accounts are translated at average exchange rates during the year. F-13 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Resulting translation adjustments are reported as a component of other comprehensive income in stockholders' equity. Foreign currency transaction gains and losses resulting from the effect of exchange rate fluctuations on transactions in currencies other than the functional currency are included in the determination of net earnings. The Company has no material foreign currency transaction gains or losses for any of the periods presented in these financial statements. Property and Equipment--The Company uses the successful efforts method of accounting for its oil and gas properties. Under this method of accounting, the tangible and intangible development costs of productive wells and development dry holes are capitalized, and dry hole costs on exploratory wells are charged against income when the well is determined to be non-productive. Other exploratory expenditures, including geological and geophysical costs and delay rentals, are expensed as incurred. The cost of unevaluated leasehold acquisitions and wells in progress are included in unproven properties pending evaluation. Depreciation and depletion of producing oil and gas properties are computed separately on each individual property on the unit-of-production method based on estimated proved reserves. Depreciation of other property and equipment is computed on the straight-line method over the estimated useful lives of the assets ranging from 3 to 7 years. For U. S. onshore properties, the Company estimates that residual salvage values of equipment approximate any future dismantlement, restoration and abandonment costs. For Canadian onshore properties, the Company provides for estimated dismantlement, restoration and abandonment on a unit of production basis. For offshore properties, the Company has fully provided for estimated dismantlement, restoration and abandonment costs. Maintenance and repairs are charged to expense as incurred. Long-Lived Assets--Long-lived assets to be held and used are reviewed for impairment whenever events or changes in circumstances indicate that the related carrying amount may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset to future net cash flows expected to be generated by the asset based on Company's engineering estimates of proved reserves and the Company's estimates of future oil and natural gas prices. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which carrying amount of the assets exceed the fair value of the assets. Fair value is estimated to be the net present value of the future cash flows based on year-end proved reserves and management's estimate of future prices. There were no impairment charges in the year ended December 31, 2000. During 1999 the Company recorded pre-tax impairment charges of $8,686,000 related to its oil and gas properties in the U.S. and Canada. Approximately $3,386,000 of the impairment charge resulted from downward revisions of the Company's proved undeveloped reserves. The year-end estimates as of December 31, 1999 were negatively affected relative to amounts previously reported due to downward revisions, totaling 492,816 BOE, related to the Company's properties in the U.S. totaling 368,500 BOE and in Canada totaling 124,316 BOE. The U.S. revisions resulted from differences in the interpretation between the current and predecessor independent engineering firms. The Canadian revisions resulted primarily from decreased production performance in 1999. These differences, many of which relate to classification of reserves within the different oil and gas reserve categories (i.e. proved, probable and possible) are due to the numerous engineering, geological and operational assumptions that generally are derived from limited data. In addition, approximately $5,300,000 of the 1999 impairment resulted from the pre-tax adjustments of Neutrino's cost basis to the net realized value of the sale of Inverness and Swan Hills in March 2000. During 1998, the Company recorded pre-tax impairment charges of $9,344,000 as a result of its determination of future cash flows based on lower oil price assumptions than previously applied. F-14 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Environmental Liabilities--Environmental related costs, if any, are capitalized or expensed as appropriate. Environmental costs, if any, that relate to past events and are not associated with future production are expensed when incurred. Income Taxes--The Company accounts for income taxes using the asset and liability method. The asset and liability method requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of temporary differences between financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates in effect for the year in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized as part of the provision for income taxes in the period that includes the enactment date. Cash Equivalents--Management considers all highly liquid investments with a maturity of three months or less when purchased to be cash equivalents. Use of Estimates in the Preparation of Financial Statements--The preparation of financial statements in conformity with generally accepted counting principles require management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Stock-Based Compensation--The Company accounts for stock-based compensation using the intrinsic value method prescribed by Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to Employees" ("APB 25"), and related Interpretation, and has provided pro forma disclosures of net earnings and earnings per share in accordance with the provisions of Statement of Financial Accounting Standards No. 123, "Accounting for Stock-Based Compensation" ("SFAS 123"). Compensation cost for stock options is measured as the excess, if any, of the quoted market price of the Company's stock at the date of the grant over the exercise price of the option. Use of Commodity Derivatives--The Company may use derivative instruments, such as futures, swaps and options, to manage its exposure to commodity price risk and interest rate risk. Derivatives that qualify a hedges and held for non-trading purposes are accounted for using the deferral method of accounting. For a commodity derivative to qualify as a hedge, the price movements in the commodity derivative must be highly correlated with the underlying hedged commodity. Under this method of accounting, gains and losses are not recognized until the underlying physical transaction occurs. Deferred gains and losses related to such instruments are reported on the consolidated balance sheet as assets or liabilities. The Company does not typically directly enter into derivative contracts for the purposes of speculating on commodity price changes or interest rate changes. Contracts held for trading purposes, or contracts which do not qualify as hedges, are accounted for using the mark-to-market method. Under this methodology, contracts are reported on the consolidated balance sheet at fair value as assets or liabilities with the changes in fair value recognized in current period income. The Company monitors open derivative positions with a strict policy which limit its exposures to market risk and require reporting to management of potential financial exposure. Effective January 1, 2001, the Company adopted Statement of Financial Accounting Standards No. 133 ("SFAS 133"), Accounting for Derivative Instruments and Hedging Activities, and SFAS No. 138, Accounting for Certain Derivative Instruments and Certain Hedging Activities, an amendment of FASB Statement No. 133. These statements establish accounting and reporting standards requiring that derivative instruments, including certain derivative instruments embedded in other contracts, be recorded on the balance sheet at fair value as either assets or liabilities. The accounting for changes in the fair value of a derivative instrument depends on F-15 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) the intended use and designation of the derivative at its inception. Special accounting for qualifying hedges allows a derivative's gains and losses to offset related results of the hedged item in the statement of operations, and requires the Company to formally document, designate and assess the effectiveness of the hedge transaction to receive hedge accounting. For derivatives designated as cash flow hedges, changes in fair value, to the extent the hedge is effective, are recognized in other comprehensive income until the hedged item is recognized in earnings. Overall hedge effectiveness is measured at least quarterly. Any changes in the fair value of the derivative instrument resulting from hedge ineffectiveness, as defined by SFAS 133 and measured based on the cumulative changes in the fair value of the derivative instrument and the cumulative changes in the estimated future cash flows of the hedged item, are recognized immediately in earnings. The Company has designated all of its commodity hedges as cash flow hedges. Adoption of SFAS 133, at January 1, 2001, resulted in the recognition of $197,000 of derivative assets and $3.3 million of derivative liabilities on the Company's balance sheet and $1.9 million, net of taxes, of hedging losses included in accumulated other comprehensive income as the cumulative effect of a change in accounting principle and $796,000 million, net of taxes, recorded as a cumulative effect of change in accounting principle to net income. Amounts are determined as of January 1, 2001 based on market quotes and the Company's portfolio of derivative instruments. Earnings (loss) per Share--Basic earnings per share is based on the weighted average shares outstanding without any dilutive effects considered. Diluted earnings per share reflects dilution from all potential common shares, including options and convertible debt. On August 1, 2000, pursuant to the plan of reorganization of the Bankruptcy Code, old shareholders of the Company's common stock received one share of the Company's new common stock for each five shares of the Company's old common stock. All share and per-share amounts have been restated to reflect the 1 for 5 August 1, 2000 reverse stock split. See Note 2 Bankruptcy Filing. Earnings per share have been calculated on the restated weighted average number of shares outstanding for the years ended December 31, 2000, 1999 and 1998, respectively. For the year ended December 31, 2000, 1999 and 1998, respectively, the issuance or conversion of potential common shares of 4,087,437, 16,451 and 138,600 would have had an antidilutive effect on the diluted earnings per share calculation and therefore were not considered in the calculation of the diluted weighted average number of shares outstanding. Reclassifications--Certain amounts in prior financial statements have been reclassified to conform to the 2000 financial statement presentation. Comprehensive Income--Comprehensive income includes all changes in a company's equity except those resulting from investments by owners and distributions to owners, including, among other things, foreign currency translation adjustments. The Company's total comprehensive income (loss) for the years ended December 31, 2000, 1999 and 1998 was as follows (in thousands): Years Ended December -------------------------- 2000 1999 1998 ------- ------- -------- Net income (loss)............................ $10,854 $(5,758) $(16,409) Foreign currency translation adjustment...... (995) 2,016 (2,077) ------- ------- -------- Total comprehensive income (loss)............ $ 9,859 $(3,742) $(18,486) ======= ======= ======== F-16 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Note 2. Bankruptcy Filing On October 29, 1999, the Company and its Debtor Subsidiaries, which excluded Neutrino, filed voluntary petitions for relief under the Bankruptcy Code in order to facilitate the restructuring of the Company's long-term debt, revolving credit, trade debt and other obligations. The filings were made in the U.S. Bankruptcy Court for the Southern District of Texas, Victoria Division. The Company and its Debtor Subsidiaries emerged from bankruptcy on August 1, 2000. All debts of the Company and its Debtor Subsidiaries as of the Petition Date were stayed by the bankruptcy petitions and were subject to compromise pursuant to such proceedings until the Effective Date. The Company and its Debtor Subsidiaries operated as debtors-in-possession subject to the Bankruptcy Court's supervision and orders. The proceedings of the Company and its Debtor Subsidiaries were consolidated for administrative purposes. The decision to seek protection was taken by the Company and its Debtor Subsidiaries because the Company concluded that a restructuring of its indebtedness could not be completed without the protection and assistance of the Bankruptcy Court. Timing of the bankruptcy filing was imposed by several factors, including the possible acceleration of the Company's $16.1 million of indebtedness by its domestic bank creditors and the inability of the Company and its debenture holders to reach a satisfactory compromise regarding the consideration to be received in the previously proposed restructuring. The bankruptcy petitions were filed in order to preserve cash and to give the Company the opportunity to restructure its debt. On February 25, 2000, the Company filed a Plan of Reorganization and Disclosure Statement and on May 2, 2000 filed a Second Amended Plan ("Amended Plan"). The Amended Plan set forth the means for satisfying claims, including liabilities subject to compromise and interests in the Company. On May 2, 2000, the Bankruptcy Court held a hearing and approved the Disclosure Statement and the procedure for transmitting the Amended Plan and Disclosure Statement for acceptance or rejection to all affected parties. The Bankruptcy Court set June 30, 2000 for the hearing on confirmation of the Amended Plan. On July 5, 2000, the Company announced an agreement among all parties contesting its Amended Plan to support modifications to its Plan ("Modified Plan") to emerge from bankruptcy. The Bankruptcy Court set July 19, 2000 to complete the confirmation hearing on the Modified Plan subject to certain restrictions and on July 21, 2000 entered the order confirming the Company's Modified Plan. The Modified Plan became effective on August 1, 2000. The Modified Plan generally provided for the satisfaction of the Company and Debtor Subsidiaries' claims including payment of all Bankruptcy Court approved administrative expenses as follows: . Domestic secured debt was paid in full with interest and expenses including default interest of 3.5% from the Petition Date with proceeds from a new secured credit facility secured by the Company. Payment of the domestic secured debt, interest and expenses was $16,882,511 and occurred on August 23, 2000. . All other creditors other than domestic secured debt and amounts owed debenture holders are to be paid in cash over periods ranging from 1 to 14 months. . Debenture holders were satisfied as follows: . Cash payment of $5 million, which was made to the indenture trustee on August 31, 2000. . Issuance of common stock that when issued represented approximately 78% of the Company's outstanding common shares (9,536,422 shares). . A new Board of Directors was appointed for a one year term as follows: one by the creditors' committee, two from the existing board, three by representatives of significant owners of debentures and one jointly by the creditors' committee and significant owners of debentures. F-17 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) . A 1:5 reverse stock split of the Company's outstanding common stock, par value $0.01 per share, was effectuated on August 1, 2000, the Effective Date. Subject to the effects of the reverse split, the existing common stock, options and warrants remained outstanding with no change in terms and conditions except that all options and warrants expiring between the Petition Date and confirmation of the Modified Plan were extended for a two year period. . The current common shareholders, option holders, and warrant holders of record on July 24, 2000, received approximately 3,667,000 warrants allowing them to increase their ownership from 22% to up to 40% of the outstanding common stock. The new warrants are for a perpetual term with an exercise price of $4.21 per share, subject to adjustment for certain customary anti-dilution stock splits, stock dividends and other recapitalization events. The exercise price must be paid in cash. Pursuant to the provisions of SOP 90-7, the Company did not adopt fresh- start reporting upon its emergence from Bankruptcy. Based on the closing price of the Company's common stock on the Modified Plan confirmation date (July 21, 2000), the satisfaction of the $41.4 million debentures and accrued interest of $1.6 million through the issuance of 9,536,422 shares of the Company's common stock, par value $0.01, per share and cash of $5 million resulted in an extraordinary gain of approximately $8.3 million, which is reflected in the December 31, 2000 statement of operations. In addition, the $616,000 fair value of the warrants issued was charged to bankruptcy expenses. Note 3. Acquisitions and Divestitures Neutrino On June 23, 1998, the Company agreed to acquire 92.3% of the outstanding common shares of Neutrino, which was effective as of June 30, 1998 and funded on July 2, 1998. On July 3, 1998, the Company initiated a compulsory acquisition of the remaining shares outstanding, which was effective as of June 30, 1998 and funded on July 21, 1998. The Company acquired Neutrino through a cash tender offer for the common shares outstanding, and assumed Neutrino's bank debt and working capital deficit. Neutrino is an independent oil and gas company located in Calgary, Canada. The merger was accounted for as a purchase.

(9,562,000) ----------- $57,198,000 =========== Following the acquisition of Neutrino, the purchase price was reduced to reflect the proceeds from the sale of non-strategic assets in the amount of $3,390,000. The following is a reconciliation of the net cash paid in connection with the acquisition of Neutrino: Cash consideration for common stock.......................... $34,091,000 Cash paid for legal, accounting and transaction costs........ 1,705,000 Cash paid for other closing costs............................ 130,000 ----------- $35,926,000 =========== F-18 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Amerac On January 28, 1998, the shareholders of both the Company and Amerac Energy Corporation ("Amerac") approved the merger of Amerac into a subsidiary of the Company. Pursuant to the merger agreement, the Company issued 3,333,333 shares of its Common Stock to acquire the common stock of Amerac and assumed Amerac's outstanding debt, which was approximately $8,700,000. The debt was retired upon consummation of the acquisition. The merger was effective on January 28, 1998, and was accounted for as a purchase. The total purchase price was approximately $24,820,000 and consists of the following: Issuance of Common Stock..................................... $15,433,000 Debt assumed and working capital............................. 8,714,000 Legal, accounting and transaction costs...................... 673,000 ----------- $24,820,000 =========== The following is a reconciliation of the net cash paid in connection with the acquisition of Amerac: Cash paid for assumed debt at consummation of acquisition... $8,714,000 Cash paid for legal, accounting and transaction costs....... 673,000 ---------- $9,387,000 ========== Subsequent to the acquisition of Amerac, the purchase price was reduced by $7,919,000 for the sale of non-strategic assets, including Amerac's Golden Trend properties for $6,969,000 on June 30, 1998 and the Riffe Field for $510,000 on July 1, 1998. Big Escambia Creek During 1997 and 1998, the Company acquired interests in the Big Escambia Creek Field and surrounding area in a series of six transactions. The largest acquisition was the purchase of the outstanding capital stock of BEC Energy, Inc. on May 10, 1997, for $10,640,000. BEC's assets consisted of working interests in fourteen oil and gas wells located in the Big Escambia Creek Field, Escambia County, Alabama. Thereafter, the Company acquired additional working interests in the area for $12.1 million. Each acquisition was accounted for as a purchase. Divestitures On July 21, 1999 the Company agreed to sell properties consisting of certain proven and unproven property interests in Texas to ANR Production Company. The properties include all of the Company's interest in the Brushy Creek and Texan Gardens Fields in Dewitt, Lavaca and Hidalgo counties of Texas. In July and August of 1999, the sale of its interests in the Brushy Creek Field and Texan Gardens Field were closed for $15.2 million and $0.8 million, respectively. The sale of interests in Brushy Creek resulted in a gain of approximately $10.6 million and Texan Gardens Field a loss of approximately $3.4 million. Neutrino sold in the fourth quarter of 1999 its interest in two non-core properties in Alberta, Canada for approximately $3.7 million, resulting in a loss of sale of approximately $207,000. In March 2000, Neutrino sold its interest in Inverness and Swan Hills in Alberta, Canada, for $9.0 million. These assets were classified as properties held for sale and are included in current assets at December 31, 1999. The Company recorded as an impairment of approximately $5.3 million in 1999 to adjust the cost basis of Inverness and Swan Hills to their net realized value based on the estimated sales price received in March 2000. F-19 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Pro forma The following table summarizes the pro forma (unaudited) results (stated in thousands, except per share data), of the Company as though the dispositions of Brushy Creek, Texan Gardens and Inverness/Swan Hills had occurred on January 1, 1999.

During 1999, the Company made additional acquisitions, none of which would have had a material effect on the historical results of operations of the Company. During the first quarter of 1999, the Company sold its mineral interests and substantially all of its royalty interests in Texas, Mississippi and New Mexico for approximately $6,000,000. These divestitures would not have had a material effect on the Company's historical results of operations. Note 4. Debt Debt consisted of the following (in thousands): December 31, --------------- 2000 1999 ------- ------- Domestic Credit Facility................................. $14,282 $ -- Old domestic credit facility--in default................. -- 16,109 Canadian credit facility (U.S. Dollars).................. 2,532 -- Old Canadian credit facility (U.S. Dollars).............. -- 13,876 Convertible subordinated debentures--in default.......... -- 41,400 ------- ------- Total indebtedness..................................... $16,814 $71,385 ======= ======= As described in Note 2, because of the Company's filing of Chapter 11, all amounts as of December 31, 1999 were subject to compromise, except for its Canadian bank credit facility, which was reflected as a current liability not subject to compromise on the Consolidated Balance Sheet. On August 23, 2000, the Company entered into a new credit facility ("Domestic Credit Facility") with a domestic lender in the principal amount of up to $30,000,000. At December 31, 2000, the Domestic Credit Facility provides for a borrowing base of $17,625,000 and matures on August 23, 2003. Proceeds from the Domestic Credit Facility were used to repay the prior domestic facility as provided in the Modified Plan. The obligations under the Domestic Credit Facility are secured by substantially all of the assets of the Company and its subsidiaries other than Neutrino. The Domestic Credit Facility prohibits the payment of dividends and contains covenants relating to the financial condition of the Company, including working capital, tangible net worth and cash flow coverage covenants. At December 31, 2000, the outstanding borrowing was $14,282,512. On March 7, 2001 outstanding borrowings under the Domestic Credit Facility were $13,582,512 with borrowing availability of $3,767,488. Outstanding principal under the Domestic Credit Facility bears interest at F-20 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) the Bank Index Rate plus 0.5% (10.0% at December 31, 2000) to the extent of the borrowing base utilized. The borrowing base is redetermined semi-annually in May and November at the sole discretion of the domestic lender. The Company may request four additional borrowing base redeterminations during any calendar year except that no more than one redetermination will be made each calendar quarter. On August 29, 2000, Neutrino repaid its prior Canadian credit facility and entered into a new loan facility in the principal amount of up to US $30,000,000 loan facility (the "Canadian Credit Facility") with a new Canadian lender. At December 31, 2000 the borrowing base under the Canadian Credit Facility is US $10,075,000 and is due August 29, 2003. At December 31, 2000, outstanding borrowings under the Canadian Credit Facility were US $2,531,814. The Canadian Credit Facility is secured by substantially all of Neutrino's assets and guaranteed by the Company. On March 7, 2001, outstanding borrowings under the Canadian Credit Facility were US $1,950,000 (Cdn $3,000,000) with a borrowing availability of US $7,940,000 (Cdn $12,215,384). Outstanding principal under the Canadian Credit Facility bears interest at the bank's prime rate plus 0.5% (8.0% at December 31, 2000) to the extent of the borrowing base utilized. The Canadian Credit Facility contains certain covenants relating to the financial condition of Neutrino, including working capital, tangible net worth and cash flow coverage covenants. The borrowing base under the Canadian Credit Facility is subject to semi-annual redeterminations beginning November 2000. The borrowing base is redetermined semi-annually beginning November 2000 and will be made at the sole discretion of the Canadian lender. Neutrino may request four additional borrowing base redeterminations during any calendar year except that no more than one redetermination will be made each calendar quarter. On October 2, 1997, the Company issued $41,400,000 of 6.875% convertible subordinated debentures due on October 1, 2007. The debentures were convertible into Common Stock of the Company at any time prior to maturity, at a conversion price of $8.26 per share. Proceeds of the offering were used to reduce bank debt and fund subsequent acquisitions. Pursuant to the debenture agreement, in the event of a change of control of the Company, debenture holders had the right to require the Company to repurchase the security at face value plus accrued interest. Due to the bankruptcy filings on October 29, 1999, the Company was not in compliance with certain provisions of the debenture agreement at December 31, 1999. Pursuant to the Modified Plan, the debentures were extinguished and converted in exchange for $5 million in cash and approximately 78% of the common stock of the Company. Based on the closing price of $3.125 of the Company's common stock on the Modified Plan confirmation date, the exchange of the $41.4 million of debentures and accrued interest of approximately $1.6 million for cash of $5 million and 9,536,422 shares of common stock resulted in an extraordinary gain, net of tax, of $8,258,993. See Note 2--Bankruptcy Filing. Note 5. Fair Value of Financial Instruments The Company has estimated the fair value of financial instruments based on arms length transactions or quoted market values. The estimated fair values are summarized below (in thousands): Years Ended December 31, -------------------------------------- 2000 1999 ------------------ ------------------ Book Fair Book Fair Value Value Value Value -------- -------- -------- -------- Assets/(Liabilities) Debt............................ $(16,814) $(16,814) $(71,385) $(44,061) Commodity hedges, net........... -- (3,136) -- -- Interest rate swap..............

F-21 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Note 6. Derivative Financial Instruments During 1998 and 1999, the Company entered into natural gas and oil price swaps and collars with third parties to hedge a portion of its production from the effects of fluctuations in the market price of natural gas and oil. Due to the bankruptcy filing, all third-party oil and gas hedges were cancelled by the counter-parties to these contracts, resulting in the Company's recognition of a loss of approximately $163,000 during 1999. Subsequent to the Company's emergence from bankruptcy and as required by the Company's Domestic and Canadian Credit Facilities, the Company has entered into the following crude oil and natural gas costless collars in 2000. Oil Hedges U.S. $ NYMEX WTI Monthly ------------- Period Total Bbl Bbl Floor Cap ------ ---------- ---------- ------ ------ United States Jan-01--Dec-01........................... 132,400 11,033 $22.00 $32.20 Jan-02--Sep-02........................... 88,200 9,800 $22.00 $25.60 Canada Jan-01--Dec-01........................... 111,100 9,258 $22.00 $33.30 Jan-02--Sep-02........................... 70,300 7,811 $22.00 $27.00 Gas Hedges US $ Houston Ship Period Channel ------ Total Monthly ------------- Mmbtu Mmbtu Floor Cap ---------- ---------- ------ ------ United States Jan-01--Mar-01........................... 285,000 95,000 $ 2.75 $ 6.85 Apr-01--Oct-01........................... 600,000 85,714 $ 2.75 $ 4.98 Nov-01--Mar-02........................... 378,000 75,600 $ 2.75 $ 4.85 Apr-02--Oct-02........................... 466,000 66,571 $ 2.75 $ 3.80 CDN $ Alberta Period Spot-AECO ------ Total Monthly ------------- Gigajoules Gigajoules Floor Cap ---------- ---------- ------ ------ Canada Jan-01--Sep-02........................... 1,050,000 50,000 $ 4.05 $ 6.15 Based on analysis utilizing actual derivative contractual terms at December 31, 2000, a 10% change in oil and gas prices would not have a material adverse effect on the financial position or results of operations of the Company relating to collars. The Company uses the deferral method of accounting for its natural gas and oil price swaps and collars and, therefore, 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 market price. The fair value at December 31, 2000 of collars was a net unrealized loss of approximately $3.1 million. F-22 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) At December 31, 2000, the Company held an interest rate swap that was originally intended to hedge the variability of interest expense associated with the Company'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 Cdn $15 million. The interest rate swap does not qualify for hedge accounting at December 31, 2000 and the Company has recorded the swap's fair value loss of $94,000 as a liability and an expense for the year ended December 31, 2000.

(7,593) (4,240) ------- -------- Net deferred tax liability............................ $(6,490) $ (4,240) ======= ======== In 1998, the Company acquired Amerac, which had regular tax net operating loss ("NOL") carryforwards of approximately $139,827,000 and alternative minimum tax ("AMT") NOL carryforwards or $112,687,000, as of December 31, 1998. During 1999, in connection with the Company's filing of its 1998 US Consolidated Federal Income Tax Return, the Company elected under Internal Revenue Code("IRC") Section 1502 to relinquish $114,234,000 of the regular tax NOL carryforwards and $94,859,000 of the AMT NOL carryforwards related to Amerac. The relinquishment had no effect on the Company's Consolidated Statement of Operations as the deferred tax asset related to these NOL carryforwards was fully offset by a valuation allowance for the year ended December 31, 1998. The Company has a full valuation allowance related to the remaining NOL carryforward to reduce the corresponding deferred asset, since it is more likely than not that this NOL carryforward will not be realized. The restructuring and emergence from bankruptcy will cause the Company's net operating losses to be subject to certain limitations under IRC Section 382. F-24 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The extraordinary item from extinguishment of debt includes no tax expense or benefit. The valuation allowance for deferred tax assets as of December 31, 2000 and 1999 was $5,278,000 and $10,314,000, respectively. The net change in the total valuation allowance for the year ended December 31, 2000, 1999 and 1998 was $5,036,000, ($42,924,000) and $52,509,000, respectively. Of the $42,924,000 net change in the valuation allowance for the year ended December 31, 1999, $38,840,000 was caused by the relinquishment of a portion of the Amerac NOL carryforwards as discussed above and had no effect on the Company's Consolidated Statement of Operations. In addition, the Company wrote off the deferred tax asset and corresponding valuation allowance, totaling $4,588,000, for the statutory depletion carryforwards received in the Amerac acquisition, since these carryforwards will never be realized. The remaining change of $504,000 is reflected in the rate reconciliation schedule. In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in making this assessment. In order to realize any of the deferred tax asset, the Company will need to generate sufficient future taxable income prior to the expiration of the net operating loss carryforwards in 2020. Based upon the level of historical taxable income, the Section 382 limitations and projections for future taxable income over the periods which the deferred tax assets are deductible, management believes it is more likely than not the Company will be unable to fully utilize the benefits of these deductible differences and has therefore established the valuation allowance set forth above. For federal tax purposes, the Company had a net operating loss carryforward ("NOL") of approximately $16,078,000 and $23,398,000 at December 31, 2000 and 1999. These NOLs are limited under Section 382 and must be utilized prior to their expiration, which is between 2001 and 2020. The Company also has statutory depletion carryforwards of $1,638,000 and $1,160,000 at December 31, 2000 and 1999, respectively. Note 8. Related Party Transactions In conjunction with the acquisition of Neutrino in July, 1998, 324,430 shares of Southern Mineral Common Stock, a value of approximately $1,095,000, were issued to key Neutrino management personnel in consideration for retention and other obligations. In September 1995, the Company entered into the Southern Links Group Joint Venture ("Southern Links"), to acquire, develop and market exploration prospects. The Company's joint venture partner is The Links Group, Inc. ("Links"), a company that is controlled by Robert Hillery, a former director of the Company. The Company agreed to fund the third party costs of Southern Links. Any proceeds from the sale of prospects or oil and gas from such prospects is distributed 100% to the Company until it receives an amount equal to the return of its invested capital, after which time all such proceeds and property interests, if any, are to be distributed 75% to the Company and 25% to Links. In December 1998, the Company made the determination to discontinue further evaluation of certain non-producing State of Texas offshore leases which were held within the Southern Links Venture. Such leases were scheduled to expire in January 1999 unless additional rental payments were made. Pursuant to the Joint Venture agreement, the Company assigned six State of Texas leases to Links for nominal cash consideration and retention of an overriding royalty interest of 1% of the leases. As of December 31, 1999 and 2000 the Company had no carrying costs subject to recovery related to Southern Links. The Company received no proceeds from the sales of prospects associated with Southern Links during 2000, 1999 or 1998. F-25 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) SMC Production Company, a wholly-owned subsidiary of the Company, owns an 18.906% interest in Diverse GP III ("Diverse") a general partnership. Two of the Company's directors and a third is a former director and are managers of Diverse and through various entities own the majority of the remaining interest in Diverse. The carrying value of the Company's investment in Diverse as of December 31, 2000 is approximately $2.3 million. The Company accounts for this oil and gas partnership using the proportional consolidation method. The Company received net distributions from Diverse of $497,000; $257,000 and $301,000 during the years ended December 31, 2000, 1999 and 1998, respectively. Note 9.

Stock Options and Common Stock During 1997 and 1996, the Company granted options exercisable for 34,000 and 26,000 shares of common stock, respectively, under the Company's 1996 Stock Option Plan ("1996 SOP"). Pursuant to the 1996 SOP, the Company may grant options to purchase up to 60,000 shares (subject to customary anti-dilution adjustments) of its common stock to key employees of the Company. The 1996 SOP is administered by the Compensation Committee of the Company's Board of Directors, which generally has authority to establish who receives options and the terms and conditions thereof, including vesting and exercise price. The exercise price of each option granted in 1996 is the market price for the common stock on the date of grant, determined by reference to the most recent closing price thereof reported on the Nasdaq System. During 1999, 1998 and 1997, the Company granted options exercisable for 24,500, 71,840 and 27,000 shares of common stock, respectively, under the Company's 1997 Stock Option Plan ("1997 SOP"). Pursuant to the 1997 SOP, the Company may grant options to purchase up to 140,000 shares (subject to customary anti-dilution adjustments) of its common stock to key employees of the Company. The 1997 SOP is administered by the Compensation Committee of the Company's Board of Directors, which generally has authority to establish who receives options and the terms and conditions thereof, including vesting and exercise price. The exercise price of each option granted in 1997 is the market price for the common stock on the date of grant, determined by reference to the most recent closing price reported on the Nasdaq Systems. The 1996 and 1997 Stock Option Plans were amended on December 21, 1998 to provide for the exchange and repricing of all the outstanding options held by current Company employees, except the President and CEO, for new options exercisable at a price lower than that of the cancelled options, bearing the same exercise term. The exercise price for the repriced options equaled $5.00, which was higher than the $3.125 per share closing price of the Company's common stock on the date of grant, and thus there was no impact of the repricing on the December 31, 1998 financial statements. In conjunction with severance arrangements with certain officers and employees in 1999, the Company repriced 61,000 shares at the current market price of $1.40, granted full vesting and extending the expiration date to August 31, 2001. Because the options were repriced to the market price at the date of grant, there was no impact of these modifications on the December 31, 1999 financial statements. F-26 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) During 1998, and in conjunction with the acquisition of Neutrino, the Company granted Non-Qualified Stock Options exercisable for 110,000 shares of common stock under individual agreements with key members of Neutrino management. The issuance of these Non-Qualified Stock options was administered by the Compensation Committee of the Company's Board of Directors which generally has authority to establish who receives options and the terms and conditions thereof, including vesting and exercise price. The exercise price of each non-qualified option granted in 1998 was at the market price for the Company's Common Stock on the date of the grant. However, in conjunction with repricing of options pursuant to the 1996 and 1997 SOP, as described above, the option price of Non-Qualified options issued in 1998 were also repriced, to $5.00, on December 21, 1998. There was no impact on the December 31, 1998 financial statements relating to the repricing of these options as the exercise price exceeded the closing price of the Company's common stock on the date of grant. The Company granted to non-employee directors stock pursuant to a directors compensation plan. During 2000, 1999 and 1998 the Company issued 96,000, 22,000 and 9,000 shares, respectively, to its directors. During 2000, the Financial Accounting Standards Board issued an Interpretation regarding APB 25 that requires that the cancellation of an option and issuance of a new option with a lower exercise price be considered in substance a modified option. Variable-plan accounting is required to be applied to the modified option from the date of the modification until the date of exercise. Consequently, the final measurement of compensation expense will occur at the date of exercise. The FASB determined that some of the provisions of the interpretation would be applied prospectively but would cover events that occur after December 15, 1998. As the option repricings described above, occurred after December 15, 1998, the new option grants qualify for variable- plan accounting at each quarterly reporting date, beginning July 1, 2000 and continuing until the options are exercised or cancelled. With the implementation of FASB Interpretation No. 44, Accounting for Certain Transactions Involving Stock Compensation, the Company recorded approximately $175,000 of compensation expense in 2000. During 1999 and 1998, the Company granted options exercisable for 1,137 and 1,042 shares of common stock, respectively, under the Company's 1996 Employee Stock Purchase Plan ("SPP"). The SPP is intended to constitute an "employee stock purchase plan" within the meaning of Section 423 of the Internal Revenue Code of 1986, as amended. Pursuant to the SPP, the Company may grant options to purchase up to 60,000 shares (subject to customary anti-dilution adjustments) of its common stock to employees of the Company. Options may be granted on January 1 and July 1 of each year to eligible employees who elect to participate in the SPP. The term of each option is six months from the date of grant. The number of options granted to each participant equals the quotient of (i) the total payroll deductions authorized by the participant during the applicable option period, divided by (ii) 85% of the fair market value of the common stock as of the date of grant of such option. The exercise price of options under SPP is 85% of the fair market value of the common stock as of the date of grant or the date of exercise of such option, whichever is less, determined by reference to the most recent closing price reported on the Nasdaq Systems. F-27 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) The Company applies APB 25 and related Interpretations in accounting for stock-based compensation. Had compensation costs been determined based on the fair value at the grant dates for awards, consistent with the method of prescribed in SFAS 123, the Company's net income and earnings per share would have been reduced to the pro forma amounts indicated below (in thousands, except per share amounts): 2000 1999 1998 ------- ------- -------- Net income (loss).................

There were no compensatory stock options granted during 2000. 1999 1998 -------------- ------------- Expected volatility.......................... 65.88% 65.63% Risk free interest rate...................... 5.00% to 5.63% 4.48 to 5.47% Expected life of options..................... 1 to 3 years 3 years Expected dividend yield...................... 0% 0% The Company's President holds a non-qualified option to purchase 90,000 shares of the Company's common stock at a price of $5.00 per share. The option is non-assignable, and is exercisable until December, 2004. Payment for the option can be made in cash, common stock of the Company, or a combination thereof. In consideration for initiating the transactions pursuant to which the Company acquired Diverse Production Company ("DPC"), the Company granted a former director of the Company an option to acquire 8,775 shares of the Company's common stock at $5.00 per share exercisable through June 2002. The Company accounted for the option grants to these directors under APB 25 and related interpretations and because the exercise price was in excess of the market price at the grant date, there was no financial statement impact at issuance of these options. In connection with the acquisition of DPC in 1995, the Company granted options exercisable for 65,000 shares of its common stock at $6.25 a share through July 2002. Each of the individuals that received the options became directors of the Company in connection with the acquisition of DPC. The Company accounted for the option grants to these directors under APB 25 and related interpretations and because the exercise price was in excess of the market price at the grant date, there was no financial statement impact at issuance of these options. In conjunction with the acquisition of Amerac in 1998, outstanding warrants to purchase 95,471 shares of Amerac Common Stock were exchanged for warrants to purchase 81,244 shares of Southern Mineral Common Stock at an average price of $33.85 per share. The warrants expired November 18, 1999, but were reinstated pursuant to the Modified Plan and expire in July 2002. The current common shareholders, option holders, and warrant holders of record on July 24, 2000, were issued approximately 3,667,000 warrants in connection with the Modified Plan (see Note 2). The warrants are for a perpetual term with an exercise price of $4.21 per share, subject to adjustment for certain customary anti- F-28 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) dilution stock splits, stock dividends and other recapitalization events. The exercise price must be paid in cash. The Company also modified certain existing options in connection with the Modified Plan, including the immediate vesting of all options, extension of option terms and reinstatement of certain options. As a result of these warrant issuances and modifications, the Company charged the estimated fair value of $616,000 to bankruptcy expense during the year ended December 31, 2000. A summary of the Company's stock options and warrants as of December 31, 2000, 1999 and 1998, and changes during the years ending on those dates is presented below: 2000 1999 1998 ---------------- ---------------- ---------------- Weighted Avg.

The weighted-average fair value of compensatory options granted during 1999 and 1998 were $1.85 and $4.20, respectively, per option. The Company does not consider any of the options issued in 2000 to be compensatory.

Restructuring and Bankruptcy Costs During the third quarter of 1999, the Board of Directors of the Company concluded that the proposed restructuring plan as filed with the Securities and Exchange Commission on July 21, 1999 could not be consummated on the terms contemplated. Therefore, estimated costs of approximately $1,372,000 associated with the restructuring were expensed during the third and fourth quarters of 1999. These costs are primarily legal, accounting, financial advisory and other transaction costs related to the proposed restructuring. Since the Company's filing for bankruptcy on October 29, 1999, it has incurred costs of approximately $553,000 during the year-ended December 31, 1999 and $4,790,000 during the year-ended December 31, 2000, primarily related to legal, accounting and financial advisory services rendered in connection with the bankruptcy. In addition, $2,463,000 that was capitalized as other assets for fees and expenses related to securing the old domestic bank debt and convertible subordinated debentures were expensed during the fourth quarter of 1999 pursuant to SOP 90- 7.

F-33 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Standardized measure of discounted future net cash flows (unaudited) The information that follows has been developed by the Company pursuant to procedures prescribed by Statement of Financial Accounting Standards No. 69 of the Financial Accounting Standards Board and utilizes reserve data estimated by independent petroleum engineering firms and by the Company. The information may be useful for certain comparison purposes, but should not be solely relied upon in evaluating the Company or its performance. Moreover, the projections should not be construed as realistic estimates of future cash flows, nor should the standardized measure be viewed as representing current value. The future cash flows are based on sales prices, costs and statutory income tax rates in existence at the dates of the projections. Since future projections are inherently imprecise, material revisions to reserve estimates may occur in the future. Further, production of the oil and gas reserves may not occur in the periods assumed, and actual prices realized and actual costs incurred are expected to vary from those used. Management does not rely upon the information that follows in making investment and operating decisions; rather, those decisions are based upon a wide range of factors, including estimates of proved and probable reserves, and price and cost assumptions different from those reflected herein. The following table sets forth the standardized measure of discounted future net cash flows from projected production of the Company's proved oil and gas reserves as of December 31 (in thousands): United States Ecuador Canada Total ------------- ------- -------- --------- At December 31, 2000 Future cash inflows............... $393,777 $ 7,249 $163,186 $ 564,212 Future production costs...........

F-35 SOUTHERN MINERAL CORPORATION AND SUBSIDIARIES NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) Oil and Gas Reserve Information The following table reflects the estimated proved reserves of the Company. The Company's estimates of reserves filed with federal agencies, including the Securities Exchange Commission, agree with the information set forth below. The oil and gas reserves are principally onshore in the continental United States, Canada and Ecuador. The Company's reserve information has been based on estimates prepared by or audited by independent petroleum engineers. Netherland, Sewell & Associates, Inc. ("NSA") prepared the domestic reserve estimates as of December 31, 1998, 1999 and 2000. NSA prepared most of the domestic reserve. The Company prepared the remaining reserve estimates. Chapman Petroleum Engineering Ltd. prepared most of the Canadian reserve estimates as of December 31, 1998 and 1999 and all of 2000. Gilbert Laustsen Jung Associates Ltd. prepared the remaining Canadian reserve estimates as of December 31, 1998 and 1999. The year-end estimates as of December 31, 1999 were negatively affected relative to amounts previously reported due to downward revisions of previous estimates. The downward revisions, totaling 492,816 BOE, related to the Company's properties in the U.S. totaling 368,500 BOE and in Canada totaling 124,316 BOE. The U.S. revisions resulted from differences in interpretation between the current and predecessor independent engineering firms. The Canadian revisions resulted primarily from decreased production performance in 1999. These differences, many of which relate to classification of reserves within the different oil and gas reserve categories (i.e. proved, probable and possible) are due to the numerous engineering, geological and operational assumptions that generally are derived from limited data. As a result of the decline in world oil prices, the Company's reserves in Ecuador were not economic as of December 31, 1998 which resulted in the elimination of all units. The Company's U.S. oil reserves (including, oil, condensate and natural gas liquids) have been prepared using year-end oil prices received by the Company of $25.52, $24.31 and $9.67 per barrel and gas reserves were prepared using year-end prices received by the Company of $10.05, $2.12 and $2.17 per Mcf, as of December 31, 2000, 1999 and 1998, respectively. The Canadian reserves have been prepared using year-end oil prices received by the Company of $26.42, $22.34 and $8.71 per barrel and natural gas prices of $9.38, $2.02 and $1.72 per Mcf, as of December 31, 2000, 1999 and 1998, respectively. Ecuador reserves were prepared using a year-end oil price of $28.53 and $24.16 per barrel as of December 31, 2000 and 1999, respectively.

Merger Agreement On August 21, 2000, the Company announced the engagement of Petrie Parkman & Co. LLP and FirstEnergy Capital Corporation of Canada to evaluate strategic alternatives available to the Company in an effort to maximize shareholder value. The Company and PetroCorp Incorporated announced on December 22, 2000 that they have executed a definitive agreement regarding the Company's merger into PetroCorp. In the merger, shareholders of the Company will, at their election, receive for each share of Southern Mineral stock $4.71 per share in cash, PetroCorp common stock or a combination of cash and stock. For both companies, the merger provides strategic and economic benefits. The operations of the two companies are very complementary, with PetroCorp primarily operating in the Gulf Coast and Mid-continent areas of the United States and the Company primarily operating in the Gulf Coast of the United States. PetroCorp and the Company both have significant oil and gas interests in the province of Alberta, Canada. Additionally, the combined company will benefit by having a substantially greater critical mass and cost savings resulting from the consolidation of operations. In connection with the merger, PetroCorp will not be obligated to issue more than four million or less than three million shares of common stock. The merger is subject to customary conditions to closing, including obtaining shareholder and regulatory approvals and the voting of shareholders to elect to receive at least three million shares of PetroCorp stock. The transaction is anticipated to close by May 31, 2001.

As of the Effective Time, by virtue of the Merger and without any action on the part of Parent, Merger Sub, Company or the holders of any securities of Merger Sub: (a) (i) Each issued and outstanding share of Parent Common Stock will remain outstanding and will represent one validly issued, fully paid and nonassessable share of Parent Common Stock. I-2 (ii) Each issued and outstanding share of common stock, par value $0.01, of Merger Sub ("Merger Sub Common Stock") will remain outstanding and will represent one validly issued, fully paid and nonassessable share of Merger Sub Common Stock. (b) Each share of Company Common Stock held in the treasury of Company and each share of Company Common Stock owned by Parent or any Subsidiary of Parent will be canceled, and no cash, capital stock of Parent or Merger Sub, or other consideration will be delivered in exchange therefor. (c) Subject to Sections 1.5(b), 1.6, 1.7, 1.8 and 1.12, each issued and outstanding share of Company Common Stock not cancelled pursuant to Section 1.5(b) will be converted into one of the following the "Merger Consideration"): (i) for each such share of Company Common Stock (other than shares as to which a Stock Election (as defined in Section 1.6(a) has been effectively made and not revoked or lost pursuant to Section 1.6), the right to receive an amount in cash, without interest (collectively, the "Cash Consideration"), equal to $4.71, (the "Per Share Merger Consideration"); or (ii) at the election of the holder thereof, for each such share of Company Common Stock as to which a Stock Election has been effectively made and not revoked or lost, the right to receive a number of shares of Parent Common Stock equal to the Exchange Ratio (collectively, the "Stock Consideration"; the aggregate Cash Consideration and Stock Consideration issued to all of Company's shareholders in connection with the Merger will be referred to as the "Aggregate Merger Consideration"). The "Exchange Ratio" will equal the Per Share Merger Consideration divided by 10. (d) [OMITTED.] (e) If, and only if, the aggregate number of shares of Company Common Stock as to which a Stock Election has been effectively made pursuant to Section 1.6 (the "Stock Election Shares") would represent (but for the application of this Section 1.5(e)) the right to receive more than 4,000,000 shares of Parent Common Stock (the "Maximum Stock Election Number"), then the Aggregate Merger Consideration will I-3 be comprised of Stock Consideration equal to the Maximum Stock Election Number and Cash Consideration in an amount equal to the balance of the Aggregate Merger Consideration. In which case, the Stock Election Shares will be converted into the right to receive the Cash Consideration or the Stock Consideration in the following manner: (i) the number of Stock Election Shares covered by each Stock Election to be converted into Stock Consideration will be determined by multiplying the number of Stock Election Shares covered by such Stock Election by a fraction, (A) the numerator of which is the Maximum Stock Election Number, and (B) the denominator of which is the aggregate number of Stock Election Shares; (ii) all Stock Election Shares not converted into Stock Consideration in accordance with Section 1.5(e)(i) will be converted into the right to receive the Cash Consideration; and (iii) Fractional Shares resulting from the application of Section 1.5(e)(i) will be converted into Cash Consideration. (f) As a result of the Merger and without any action on the part of the holder thereof, at the Effective Time, all shares of Company Common Stock will, pursuant to Section 1.5(c), cease to be outstanding and the certificates representing such shares will be canceled and retired and will cease to exist and each holder of such shares of Company Common Stock will thereafter cease to have any rights with respect to such shares of Company Common Stock, except the right to receive, without interest, the Merger Consideration and cash for fractional shares of Parent Common Stock in accordance with Section 1.5(c) upon the surrender of a certificate representing such shares of Company Common Stock (a "Certificate"). (g) At the Effective Time, each warrant to purchase shares of Company Common Stock that is outstanding immediately prior to the Effective Time (a "Warrant") will remain outstanding and will become warrants to acquire Per Share Merger Consideration on terms set forth in the Warrant. After the Effective Time, each Warrant will represent the right to receive, upon exercise of such Warrant, an amount of cash (without interest) equal to the product of (i) the number of shares of Company Common Stock subject to such Warrant as of the Effective Time, and (ii) (A) the Per Share Merger Consideration, minus (B) the exercise price per share applicable under such Warrant. All references to Company in Company's warrant agreements with respect to Warrants will be deemed to refer to Parent and Merger Sub, and Parent and Merger Sub will assume the obligations of the Company under such warrant agreements. The other terms of each such Warrant and the applicable Company warrant agreement under which it was issued will continue to apply. (h) Each of Company's stock option plans listed in Section 1.5(h) of the Company Disclosure Schedule (collectively, the "Company Stock Plans"), and each outstanding stock option held by any current or former employee, director or consultant (an "Option"), (A) will be assumed by Parent at the Effective Time, and each Option will vest and become immediately exercisable, and will be deemed to be converted into an option to purchase a number of shares of Parent Common Stock (a "Substitute Option") equal to the number of shares of Company Common Stock subject to such Option multiplied by the Exchange Ratio (rounded to the nearest whole share, with 0.5 shares being rounded up) or (B) at the option of the holder of such Option exercisable by written notice to Company prior to the Effective Time, will be cancelled immediately prior to the Effective Time in exchange for a payment in cash as provided below (a "Cash-out Option"). The per share exercise price for each Substitute Option will be the current exercise price per share of Company Common Stock set forth in the original Option to which it relates divided by the Exchange Ratio (rounded up to the nearest full cent), and each Substitute Option otherwise will be subject to all of the other terms and conditions of the original Option to which it relates. The cash payment for each Cash-out Option will be equal to the product of (x) the number of shares of Company Common Stock subject to such Option, and (y) the excess of the Per Share Merger Consideration over the exercise price per share of Company Common Stock subject to such Option. Parent will provide to Company at the Effective Time funds to make the payments provided in the preceding sentence. Prior to the Effective Time, Company will take such additional actions as are necessary under applicable law and the applicable agreements and Company Stock Plans to effect the transactions contemplated by this paragraph. I-4 Section 1.6 Company Common Stock Elections. Subject to Sections 1.5, 1.7 and 1.8, each holder of shares of Company Common Stock (other than holders of shares to be canceled as set forth in Section 1.5(b)) will have the right to submit a request specifying the number of shares of Company Common Stock which such holder desires to have converted into the right to receive either Stock Consideration or a combination of Stock Consideration and Cash Consideration in accordance with the following procedures: (a) Each holder of shares of Company Common Stock may specify in a request made in accordance with the provisions of this Section 1.6 the number of such shares which such holder desires to have converted into the right to receive Stock Consideration in the Merger (a "Stock Election"). Each share of Company Common Stock as to which no Stock Election is in effect at the Stock Election Final Date (as defined in Section 1.6(e)) or for which a Stock Election has been made but has been revoked or withdrawn or is otherwise no longer effective will be called a "Non-Electing Share." Subject to Sections 1.7 and 1.8, the Non-Electing Shares of each holder of shares of Company Common Stock will be treated for purposes of this Agreement as if such shares were not covered by a Stock Election and, accordingly, will be converted to the right to receive Cash Consideration in accordance with Section 1.5(c)(i). (b) Parent will authorize Parent's Transfer Agent or such other person as will be reasonably acceptable to Company to receive Stock Elections, to act as exchange agent hereunder and to make, subject to approval by Parent and Company (provided such approval is not unreasonably withheld, delayed or denied), any computations required to be made to give effect to this Article I (the "Exchange Agent"). (c) Parent will prepare, for use by shareholders of Company in surrendering Certificates, a form (the "Form of Stock Election") pursuant to which each holder of Company Common Stock may make Stock Elections. As of a date on which Parent and Company can mutually agree, which date is expected to be as soon as practicable after the Company Shareholder Approval is obtained (the "Stock Election Mailing Date"), the Form of Stock Election will be mailed to shareholders of record of Company and record holders of Warrants. (d) Company and Parent will use all reasonable efforts to make the Form of Stock Election available to all persons who become shareholders of record of Company and Parent during the period between the Stock Election Mailing Date and the Stock Election Final Date. (e) A Stock Election will have been properly made only if the Exchange Agent will have received, by 5:00 p.m., New York City time, on the twentieth day (or a later date which may be determined prior to the Stock Election Mailing Date by mutual agreement of Parent and Company) following the date of mailing of the Form of Stock Election (such time on such day being referred to herein as the "Stock Election Final Date"), a properly completed and signed Form of Stock Election. A holder of Warrants that (i) receives a Form of Stock Election, (ii) exercises Warrants in accordance with the applicable warrant agreement after receipt of such Form of Stock Election but prior to the Stock Election Final Date, and (iii) otherwise delivers such Form of Stock Election in accordance with this Section 1.6(e) with respect to the shares of Company Common Stock issuable under such Warrant, will have made a Stock Election with respect to such shares of Company Common Stock issuable under such Warrant if, and only if, such shares are issued to such holder on or prior to the Stock Election Final Date so that such holder is the record holder of such shares on the Stock Election Final Date. (f) Any holder of record of shares of Company Common Stock may at any time prior to the Stock Election Final Date change such holder's Stock Election by written notice received by the Exchange Agent at or prior to the Stock Election Final Date, accompanied by a properly completed Form of Stock Election. (g) Any holder of record of shares of Company Common Stock may at any time prior to the Stock Election Final Date revoke such holder's Stock Election by written notice received by the Exchange Agent at or prior to the Stock Election Final Date or by withdrawal prior to the Stock Election Final Date of such holder's Certificates previously deposited with the Exchange Agent. Any revocation of a Stock Election may be withdrawn by notice of such withdrawal delivered at or prior to the Stock Election Final Date. Any shareholder of Company who will have deposited Certificates with the Exchange Agent will have the I-5 right to withdraw such Certificates by written notice received by the Exchange Agent at or prior to the Stock Election Final Date. Parent will obtain from the Exchange Agent an agreement to return all Stock Elections and accompanying Certificates to the shareholders submitting the same in the event this Agreement will be terminated in accordance with its terms. (h) Parent will have the right, subject to approval by Company (provided such approval is not unreasonably withheld or delayed), to make rules, not inconsistent with the terms of this Agreement, governing the validity of Forms of Stock Election, the issuance and delivery of certificates for Parent Common Stock into which shares of Company Common Stock are converted in the Merger and the payment for shares of Company Common Stock converted into the right to receive the Cash Consideration in the Merger. Section 1.7 Parent to Make Cash and Certificates Available, Transfer Taxes, Withholding. (a) As soon as practicable after the Effective Time, Parent will deposit with the Exchange Agent, in trust for the holders of shares of Company Common Stock and holders of Warrants, certificates for shares of Parent Common Stock and cash representing the Aggregate Merger Consideration payable pursuant to Sections 1.5, 1.6, and 1.8 (such certificates and cash, together with any dividends or distributions with respect thereto, being hereinafter referred to as the "Exchange Fund"). The Exchange Agent will invest any cash included in the Exchange Fund as directed by Parent on a daily basis. Any interest or other income resulting from such investments will be paid to Parent. As soon as practicable after the Effective Time, the Exchange Agent will distribute to each holder of shares of Company Common Stock converted into the right to receive the Cash Consideration or the Stock Consideration pursuant to Sections 1.5, 1.6, and 1.8, upon surrender to the Exchange Agent (to the extent not previously surrendered with a Form of Stock Election) of one or more Certificates for cancellation, a check for the amount of cash to which such holder is entitled under such sections and/or certificates representing the shares of Parent Common Stock to which such holder is entitled under such sections. As soon as practicable after the Effective Time, the Exchange Agent will mail to each holder of record of a Certificate or Certificates whose shares were converted pursuant to this Article I (other than any holder who previously surrendered all its Certificates with a Stock Election or pursuant to a guarantee of delivery delivered with a Stock Election) (A) a letter of transmittal in form reasonably acceptable to Parent (which will specify that delivery will be effected, and risk of loss and title to the Certificates will pass, only upon actual delivery of the Certificates to the Exchange Agent) and (B) instructions for use in effecting the surrender of the Certificates. (b) Upon surrender for cancellation to the Exchange Agent of a Certificate, together with such letter of transmittal, duly executed, the holder of such Certificate will be entitled to receive in exchange therefor a certificate representing that number of whole shares of Parent Common Stock issuable and/or the cash payable to such holder pursuant to Sections 1.5, 1.6 and 1.8 of this Agreement. Each share of Parent Common Stock into which a share of Company Common Stock will be converted will be deemed to have been issued at the Effective Time. If any certificate representing shares of Parent Common Stock or cash or other property is to be issued or delivered in a name other than that in which the Certificate surrendered in exchange therefor is registered, it will be a condition of such exchange that the Certificate so surrendered will be properly endorsed and otherwise in proper form for transfer and that the Person requesting such exchange will pay to the Exchange Agent any transfer or other taxes required by reason of the issuance of certificates for such shares of Parent Common Stock in a name other than that of the registered holder of the Certificate surrendered or will establish to the satisfaction of the Exchange Agent that such tax has been paid or is not applicable. Parent or the Exchange Agent will be entitled to deduct and withhold from the consideration otherwise payable pursuant to this Agreement to any holder of shares of Company Common Stock such amounts as Parent or the Exchange Agent is required to deduct and withhold with respect to the making of such payment under the Code, or under any provision of state, local or foreign tax law. To the extent that amounts are so withheld by Parent or the Exchange Agent, such withheld amounts will be treated for all purposes of this Agreement as having been paid to the holder of the shares of Company Common Stock in respect of which such deduction and withholding was made by Parent or the Exchange Agent. I-6 Section 1.8 Dividends, Fractional Shares, etc. (a) Notwithstanding any other provisions of this Agreement, no dividends or other distributions declared after the Effective Time on Parent Common Stock will be paid with respect to any shares of Company Common Stock represented by a Certificate, until such Certificate is surrendered for exchange as provided herein. Subject to the effect of applicable laws, following surrender of any such Certificate, there will be paid to the holder of certificates of Parent Common Stock issued in exchange for such Certificate, without interest, (i) at the time of such surrender, the amount of dividends or other distributions with a record date after the Effective Time theretofore payable with respect to such whole shares of Parent Common Stock and not paid, less the amount of any withholding taxes that may be required thereon, and (ii) at the appropriate payment date, the amount of dividends or other distributions with a record date after the Effective Time but prior to surrender and a payment date subsequent to surrender payable with respect to such whole shares of Parent Common Stock, less the amount of any withholding taxes that may be required thereon. (b) At or after the Effective Time, there will be no transfer on the stock transfer books of Company of the shares of Company Common Stock that were outstanding immediately prior to the Effective Time. If, after the Effective Time, certificates representing any such shares are presented to the Surviving Corporation, they will be canceled and exchanged for the Merger Consideration, if any, deliverable in respect thereof pursuant to this Agreement. (c) No fractional shares of Parent Common Stock will be issued pursuant to the Merger. In lieu of the issuance of any fractional share of Parent Common Stock pursuant to the Merger, cash adjustments will be paid to holders in respect of any fractional share of Parent Common Stock that could otherwise be issuable (each, a "Fractional Share"), and the amount of such cash adjustment will be equal to the product of such fractional amount and the Per Share Merger Consideration. (d) Any portion of the Exchange Fund (including the proceeds of any investments thereof and any shares of Parent Common Stock) that remains unclaimed by the former shareholders of Company six months after the Effective Time or for such longer time as Parent will determine will be delivered to Parent. Any former shareholder of Company who has not theretofore complied with this Article I will thereafter look only to the Surviving Corporation and Parent for payment of the applicable Merger Consideration, cash in lieu of fractional shares and unpaid dividends and distributions on Parent Common Stock deliverable in respect of each share of Company Common Stock such shareholder holds as determined pursuant to this Agreement, in each case without any interest thereon. (e) To the fullest extent permitted by law, none of Parent, Company, the Surviving Corporation, the Exchange Agent or any other Person will be liable to any former holder of shares of Company Common Stock for any amount properly delivered to a public official pursuant to applicable or unclaimed property, escheat or similar laws. (f) In the event that any Certificate will have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming such Certificate to be lost, stolen or destroyed and, if required by Parent the posting by such person of a bond in such reasonable amount as Parent may direct as indemnity against any claim that may be made against it with respect to such Certificate, the Exchange Agent will issue in exchange for such lost stolen or destroyed Certificate the applicable Merger Consideration, cash in lieu of fractional shares, and unpaid dividends and distributions on shares of Parent Common Stock, as provided in this Section 1.8, deliverable in respect thereof pursuant to this Agreement. (g) In the event of any change in the Parent Common Stock between the date of this Agreement and the Effective Time by reason of any stock split, stock dividend, subdivision, reclassification, combination, or exchange of Parent Common Stock or the like, the Per Share Merger Consideration, the Exchange Ratio and other terms set forth in this Agreement will be appropriately adjusted. I-7 Section 1.9 Closing. The closing of the Merger (the "Closing") and all actions contemplated by this Agreement to occur at the Closing will take place at the offices of Parent, 6733 South Yale Avenue, Tulsa, Oklahoma 74136, at 10:00 a.m., local time, on a date to be specified by the parties, which (subject to fulfillment or waiver of the conditions set forth in Article VI) will be no later than the second business day following the day on which the last of the conditions set forth in Article VI will have been fulfilled or waived, or at such other time and place as Parent and Company will agree. Section 1.10 Transfer Taxes. Parent and Company will cooperate in the preparation, execution and filing of all returns, applications or other documents regarding any real property transfer, stamp, recording, documentary or other taxes and any other fees and similar taxes which become payable in connection with the Merger other than transfer or other taxes described in Section 1.7(b) (collectively, "Transfer Taxes"). From and after the Effective Time, Parent will pay or cause to be paid, without deduction or withholding from any amounts payable to the holders of Company Stock, all Transfer Taxes. Section 1.11 Guarantee. Parent hereby absolutely, unconditionally and irrevocably guarantees the performance by Merger Sub of all of its obligations under this Agreement. The liability of Parent hereunder will be primary and not as a surety, and will not be affected by: (a) any amendment, modification of or supplement to this Agreement, any other Transaction Document or any agreement or any other instrument or any assignment or transfer of any rights or obligations thereunder; (b) any release or waiver, by operation of law or otherwise, of the performance or observance by Parent or Merger Sub or any Person of any express or implied agreement, covenant, term, obligation or condition under any of the Transaction Documents; (c) any extension of the time for the payment of all or any portion of any sums payable under any agreement or the extension of time for the performance of any obligations under, arising out of or in connection with any of the Transaction Documents; (d) any failure, omission, delay or lack of diligence on the part of Company, or any other Person, to enforce, assert or exercise, or any waiver of, any right, privilege, power or remedy conferred on Company or any other individual or entity by any of the Transaction Documents, or any action on the part of Company or such other Person granting indulgence or extension of any kind; (e) any bankruptcy, insolvency, readjustment, composition, liquidation, dissolution or similar proceeding with respect to Merger Sub; (f) any merger, amalgamation or consolidation of Parent or of Merger Sub into or with any other corporation or partnership or other entity or any sale, lease or transfer of any or all of the assets of Parent or of Merger Sub to any Person; or (g) any failure on the part of Company for any reason to comply with or perform any of the terms of the Transaction Documents. Notwithstanding the foregoing, Parent will not be obligated to guarantee Merger Sub's performance to the extent Parent has a defense to its performance of its obligations hereunder if such defense (i) would arise if Merger Sub were not a party to this Agreement and Company were merging into Parent, and (ii) did not arise through any act or omission of Parent. Parent hereby waives notice or demand of performance in the acceptance of its obligations hereunder. Section 1.12 Dissenting Shares. Company will give Parent prompt notice of any demands received by Company for appraisal of any shares of Company Common Stock in accordance with the GCLN, and Parent will have the right to control all negotiations and proceedings with respect to such demands except as required by applicable law. Company will not, except with the prior written consent of Parent which may be withheld in I-8 its sole discretion without any obligation to provide an explanation for the exercise of that discretion, make any payment with respect to, or settle or offer to settle, any such demands. Any such demands will not be converted into a right to receive the Merger Consideration, unless the shareholder making such demand fails to perfect or withdraws or otherwise loses its right to appraisal or it is determined that such holder does not have appraisal rights in accordance with the GCLN. If after the Effective Time such shareholder fails to perfect or withdraws or loses its right to appraisal, such shares of Company Common Stock will be treated as if they had been converted as of the Effective Time into a right to receive the Cash Consideration. ARTICLE II REPRESENTATIONS AND WARRANTIES OF PARENT Parent represents and warrants to Company as follows (such representations and warranties (as well as other provisions of this Agreement) are qualified by the matters identified on a disclosure schedule (the "Parent Disclosure Schedule") delivered by Parent to Company prior to execution of this Agreement). Section 2.1 Organization and Qualification. Parent is a corporation duly organized, validly existing and in good standing under the laws of the State of Texas and has the corporate power to carry on its business as it is now being conducted or currently proposed to be conducted. Parent is duly qualified as a foreign corporation to do business, and is in good standing, in each jurisdiction where the character of its properties owned or held under lease or the nature of its activities make such qualification necessary, except where the failure to be so qualified has not had, and would not reasonably be expected to have, alone or in the aggregate, a Parent Material Adverse Effect. For the purposes of this Agreement, a "Parent Material Adverse Effect" means any state of facts, event, change or effect which, individually or in the aggregate, (a) has a material adverse effect on the business, properties, assets, condition (financial or otherwise), liabilities or results of operations of Parent and its Subsidiaries taken as a whole, or (b) would prevent the consummation of the material transactions contemplated hereby; provided that occurrences or events arising out of or resulting from the following will in each case be excluded from consideration for purposes of the effect of an occurrence or event on Parent and its Subsidiaries, taken as a whole: (i) changes in general economic conditions, including general stock market conditions and interest rate changes, (ii) changes in the energy industry, including changes in the prices of crude oil, natural gas, natural gas liquids and other hydrocarbons produced from crude oil or natural gas ("Hydrocarbons"), or (iii) the adverse determination of any pending litigation disclosed in the Parent Disclosure Schedule. Complete and correct copies as of the date of this Agreement of the Amended and Restated Articles of Incorporation and Bylaws of Parent have been delivered to Company prior to the date of this Agreement. Section 2.2 Capitalization. The authorized capital stock of Parent consists of 25,000,000 shares of Parent Common Stock, and 1,000,000 shares of preferred stock, par value $.01 per share (the "Parent Preferred Stock"). As of the date of this Agreement, (a) 8,703,719 shares of Parent Common Stock were validly issued and outstanding, fully paid, and nonassessable, (b) no shares of Parent Preferred Stock were issued and outstanding, (c) 1,515,157 shares of Parent Common Stock were reserved for issuance pursuant to options ("Parent Stock Options") to purchase Parent Common Stock, and (d) no shares of parent Common Stock were reserved for issuance pursuant to warrants to purchase Parent Common Stock. As of the date of this Agreement, there are no bonds, debentures, notes or other indebtedness issued or outstanding having the right to vote with Parent's shareholders, whether together or as a separate class, on any matters on which Parent's shareholders may vote. As of the date of this Agreement, except for Parent Stock Options and rights ("Parent Rights") issued pursuant to the Shareholder Rights Agreement dated November 22, 1998, between Parent and First Union National Bank, there are no options, warrants, calls, convertible securities or other rights, agreements or commitments presently outstanding obligating Parent to issue, deliver or sell shares of its capital stock, or obligating Parent to grant, extend or enter into any such option, warrant, call or other such right, agreement or commitment. All of the shares of Parent Common Stock issuable in accordance with this Agreement in exchange for Company Common Stock at the Effective Time in accordance with this Agreement I-9 will be, when so issued, duly authorized, validly issued, fully paid, nonassessable and free of preemptive rights and will be delivered free and clear of all liens, claims, charges and encumbrances of any kind or nature whatsoever. Section 2.3 Subsidiaries. Each Subsidiary of Parent is a corporation, partnership or other entity duly organized, validly existing and in good standing under the laws of its jurisdiction of organization (except where the failure to be validly existing and in good standing would not be material to the business of such Subsidiary) and has the corporate or similar power to carry on its business as it is now being conducted or currently proposed to be conducted. Each Subsidiary of Parent is duly qualified to do business, and is in good standing, in each jurisdiction where the character of its properties owned or held under lease or the nature of its activities makes such qualification necessary except where the failure to be so qualified, when taken together with all such failures, has not had, and would not reasonably be expected to have, a Parent Material Adverse Effect. Section 2.3 of the Parent Disclosure Schedule contains, with respect to each Subsidiary of Parent its name and jurisdiction of organization and, with respect to each Subsidiary that is not wholly owned, the percentage of outstanding capital stock or equity capital owned by Parent or a Subsidiary. All the outstanding shares of capital stock or equity capital of each Subsidiary of Parent are validly issued, fully paid and nonassessable, and, to the extent owned by Parent or by a Subsidiary of Parent, are owned free and clear of any liens, claims or encumbrances. There are no existing options, warrants, calls, convertible securities or other rights, agreements or commitments of any character relating to the issued or unissued capital stock or other securities of any of the Subsidiaries of Parent (other than preemptive rights or similar rights held by Parent with respect to certain of its Subsidiaries). Except as set forth in Parent's Annual Report on Form 10-K for the fiscal year ended December 31, 1999, Parent does not directly or indirectly own any interest in any other corporation, partnership, joint venture or other business association or entity or have any obligation, commitment or undertaking to acquire any such interest, other than business associations customary in the oil and gas industry consisting of interests in oil and gas property subject to a joint operating agreement. Section 2.4 Authority Relative to this Agreement. Parent and each of its Subsidiaries has the corporate power to enter into this Agreement and each other agreement and document executed and delivered in connection with the material transactions contemplated hereby (together with this Agreement, the "Transaction Documents") to which Parent is a party and to carry out its obligations hereunder and thereunder. The execution and delivery of this Agreement and the other Transaction Documents to which Parent is a party and the consummation of the transactions contemplated hereby and thereby have been duly authorized by Parent's Board of Directors and the Parent Principal Shareholders. Each Transaction Document to which Parent is a party constitutes a valid and binding obligation of Parent enforceable against Parent in accordance with its terms except as enforcement may be limited by bankruptcy, insolvency or other similar laws affecting the enforcement of creditors' rights generally and except that the availability of equitable remedies, including specific performance, is subject to the discretion of the court before which any proceeding therefor may be brought. No other corporate proceedings on the part of Parent are necessary after the date of this Agreement to authorize execution by Parent of the Transaction Documents to which Parent is a party. Parent is not subject to or obligated under (a) any charter, bylaw, indenture or other loan or credit document provision, or (b) any other contract, license, franchise, permit, order, decree, concession, lease, instrument or judgment, or any statute, law, ordinance, rule or regulation applicable to Parent or any of its Subsidiaries, or their respective properties or assets, which would be breached or violated, or under which there would be a default (with or without notice or lapse of time, or both), or under which there would arise a right of termination, cancellation, modification or acceleration of any obligation, or any right to payment or compensation, or the loss of a material benefit, by its executing and carrying out the Transaction Documents to which Parent is a party other than, in the case of clause (b) only, (i) any breaches, violations, defaults, terminations, cancellations, modifications, accelerations, rights to payment or compensation, or losses which, either alone or in the aggregate, have not had, and would not reasonably be expected to have, a Parent Material Adverse Effect and (ii) the laws and regulations referred to in the next sentence. Except as required by the Securities Act of 1933, as amended (the "Securities Act"), the Securities Exchange Act of 1934, as amended (the "Exchange Act"), Canadian Governmental Entities (including without limitation Canadian Governmental Entities requiring filings under the Investment Canada I-10 Act) and the corporation, securities or blue sky laws or regulations of the various states, no filing or registration with, or authorization, consent or approval of, any court, administrative agency or commission or other governmental authority or instrumentality, domestic or foreign (each, a "Governmental Entity"), is necessary for the consummation by Parent of the Merger or the other transactions contemplated by the Transaction Documents to which Parent is a party, other than filings, registrations, authorizations, consents or approvals the failure to make or obtain which has not had, and would not reasonably be expected to have, a Parent Material Adverse Effect. Section 2.5 Reports and Financial Statements. Parent has previously furnished Company with, or there has been made available to Company, true and complete copies of its (a) Annual Reports on Form 10-K for the fiscal years ended December 31, 1998 and December 31, 1999, as filed with the Securities and Exchange Commission (the "Commission"), (b) Quarterly Reports on Form 10-Q for the quarters ended March 31, June 30 and September 30, 1999 and 2000, as filed with the Commission, (c) proxy statements related to all meetings of its shareholders (whether annual or special) since December 31, 1998, and (d) all other reports or registration statements filed by Parent with the Commission since December 31, 1998, except for preliminary material (in the case of clauses (c) and (d) above) and except for registration statements on Form S-8 relating to employee benefit plans and annual reports on Form 11-K with respect to such plans, which are all the documents that Parent was required to file with the Commission since December 31, 1998 (the documents in clauses (a) through (d) being referred to herein collectively as the "Parent SEC Reports"). All Parent SEC Reports were properly and timely filed with the Commission and any applicable securities exchange or market and its self regulatory organization. As of their respective dates, the Parent SEC Reports complied as to form in all material respects with the requirements of the Securities Act or the Exchange Act, as the case may be, and the rules and regulations of the Commission thereunder applicable to the Parent SEC Reports. As of their respective dates, the Parent SEC Reports did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. The audited consolidated financial statements and unaudited interim financial statements of Parent included in the Parent SEC Reports comply as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect thereto. The financial statements included in the Parent SEC Reports (i) have been prepared in accordance with generally accepted accounting principles applied on a consistent basis (except as may be indicated therein or in the notes thereto); (ii) present fairly, in all material respects, the financial position of Parent and its Subsidiaries as of the dates thereof and the results of their operations and cash flows for the periods then ended subject in the case of the unaudited interim financial statements, to normal year-end adjustments, any other adjustments described therein and the fact that certain information and notes have been condensed or omitted in accordance with the Exchange Act and the rules promulgated thereunder, and (iii) are in all material respects in accordance with the books of account and records of Parent and its Subsidiaries. Section 2.6 Absence of Certain Changes or Events. Except as disclosed in the Parent SEC Reports, from September 30, 2000 until the date of this Agreement, there has not been any transaction, commitment, dispute or other event or condition (financial or otherwise) of any character (whether or not in the ordinary course of business) which, alone or in the aggregate, has had, or would reasonably be expected to have, a Parent Material Adverse Effect. Section 2.7 Litigation. Except as disclosed in the Parent SEC Reports and as set forth in Section 2.7 of the Parent Disclosure Schedule, there is no suit, action or proceeding to which Parent or any of its Subsidiaries is a party pending or, to the actual knowledge of the individuals listed in Section 2.7 of the Parent Disclosure Schedule ("Parent's Knowledge"), threatened against Parent or any of its Subsidiaries which, alone or in the aggregate, has had or would reasonably be expected to have, a Parent Material Adverse Effect, nor is there any judgment, decree, injunction, rule or order of any Governmental Entity or arbitrator outstanding against Parent or any of its Subsidiaries which, alone or in the aggregate, has had, or would reasonably be expected to have, a Parent Material Adverse Effect.

Section 5.2 Registration Statement/Proxy Statement. Parent and Company will cooperate and promptly prepare, and Parent will file with the Commission as soon as practicable, a Registration Statement on Form S-4 (the "Form S-4") under the Securities Act, with respect to the Parent Common Stock issuable in the Merger (the "Parent Prospectus"), a portion of which Registration Statement will also serve as the joint proxy statement of Parent and Company (the "Joint Proxy Statement" and, together with the Parent Prospectus, the "Joint Proxy Statement/Prospectus") with respect to the Merger. The respective parties will cause the Joint Proxy Statement/Prospectus and the Form S-4 to comply as to form in all material respects with the applicable provisions of the Securities Act, the Exchange Act and the rules and regulations thereunder. Parent will use all reasonable efforts, and Company will cooperate with Parent, to have the Form S-4 declared effective by the Commission as promptly as practicable after the filing thereof (including, without limitation, responding to any comments received from the Commission with respect thereto) and to keep the Form S-4 effective as long as is necessary to consummate the Merger and the transactions contemplated thereby. Each of Parent and Company will, as promptly as practicable, provide to the other copies of any written comments received from the Commission with respect to the Joint Proxy Statement/Prospectus or the Form S-4 and advise the other of any oral comments with respect to the Joint Proxy Statement/Prospectus or the Form S-4 received from the Commission. Parent will use its best efforts to obtain, prior to the Effective Time of the Form S-4, all necessary state securities law or "Blue Sky" permits or approvals required to carry out the transactions contemplated by this Agreement and will pay all expenses incident thereto. Parent agrees that none of the information supplied or to be supplied by Parent for inclusion or incorporation by reference in the Form S-4 or the Joint Proxy Statement/Prospectus (i) in the case of the Joint Proxy Statement/Prospectus and each amendment or supplement thereto, at the time of mailing thereof, or (ii) in the case of the Parent Prospectus and each amendment or supplement thereto, at the time it is filed or becomes effective, will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. Company agrees that none of the information supplied or to be supplied by Company for inclusion or incorporation by reference in the Form S-4 or the Joint Proxy Statement/Prospectus (i) in the case of the Joint Proxy Statement and each amendment or supplement thereto, at the time of mailing thereof, or, (ii) in the case of the Parent Prospectus or any amendment or supplement thereto, at the time it is filed or becomes effective, will contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they were made, not misleading. For purposes of the foregoing, it is understood and agreed that information concerning or related to Parent will be deemed to I-31 have been supplied by Parent and information concerning or related to Company will be deemed to have been supplied by Company. No amendment or supplement to the Joint Proxy Statement/Prospectus will be made by Parent or Company without the approval (not to be unreasonably delayed, withheld or denied) of the other party. Parent will advise Company, promptly after it receives notice thereof, of the time when the Form S-4 has become effective or any supplement or amendment has been filed, the issuance of any stop order, or the suspension of the qualification of Parent Common Stock issuable in connection with the Merger for offering or sale in any jurisdiction. Section 5.3 Compliance with the Securities Act. At least 30 days prior to the Effective Time, Company will deliver to Parent a list of names and addresses of those persons who were, in Company's reasonable judgment, at the date of this Agreement, "affiliates" (each such person, an "Affiliate") of Company within the meaning of Rule 145 of the rules and regulations promulgated under the Securities Act. Company will use commercially reasonable efforts to deliver or cause to be delivered to Parent, prior to the Effective Time, from each of the Affiliates of Company identified in the foregoing list, an Affiliate Letter in the form attached hereto as Exhibit B (an "Affiliate Letter"), and Parent will duly execute the acknowledgments to any Affiliate Letters so delivered and return a copy of the acknowledged Affiliate Letter to the delivering Affiliate. Parent will be entitled to place legends as specified in such Affiliate Letters on the certificates evidencing any Parent Common Stock to be received by such Affiliates pursuant to the terms of the Agreement, and to issue appropriate stop transfer instructions to the transfer agent for the Parent Common Stock, consistent with the terms of such Affiliate Letters. Section 5.4 Stock Exchange Listing. Parent will use its best efforts to list on the AMEX, upon official notice of issuance, the Parent Common Stock to be issued pursuant to the Merger. Section 5.5 Employee Matters. As of the Effective Time, the employees of Company and each Subsidiary of Company listed in Section 5.5 of the Company Disclosure Schedule will continue employment with the Surviving Corporation and its Subsidiaries, respectively, in the same positions and at the same level of wages and/or salary and without having incurred a termination of employment or separation from service; provided, however, except as may be specifically required by applicable law or any contract, neither the Surviving Corporation and its Subsidiaries, on the one hand, nor any employee, on the other hand, will be obligated to continue any employment relationship or any specific terms of employment for any specific period of time. As of the Effective Time, Parent will assume and become the sponsor of Company Employee Benefit Plans sponsored by Company immediately prior to the Effective Time, and Parent will and will cause its Subsidiaries to satisfy all obligations and liabilities under such Company Employee Benefit Plans; provided, however, that, except as hereafter provided or in Section 5.5 of the Company Disclosure Schedule, nothing contained in this Agreement will limit or restrict Parent's or its Subsidiaries' right on or after the Effective Time to amend, modify or terminate any of Company Employee Benefit Plans. To the extent any employee benefit plan, program or policy of Parent or their affiliates is made available to any person who is an employee of Company or any of its Subsidiaries immediately prior to the Effective Time: (i) service with Company and its Subsidiaries by any employee prior to the Effective Time will be credited for eligibility and vesting purposes and for purposes of qualifying for any additional benefits tied to periods of service (such as higher rates of matching contributions and eligibility for early retirement) under such plan, program or policy and (ii) with respect to any welfare benefit plans to which such employees may become eligible, Parent will cause such plans to provide credit for any co-payments or deductibles by such employees and waive all pre- existing condition exclusions and waiting periods, other than limitations or waiting periods that have not been satisfied under any welfare plans maintained by the Company and its Subsidiaries for their employees prior to the Effective Time. At the reasonable request of Parent, Company will amend, modify or terminate any of Company Employee Benefit Plans at or immediately prior to the Effective Time (whichever the Parent may request) and will take such other steps as Parent may reasonably request to facilitate the administration after the Effective Time of the compensation and benefit plans, programs and arrangements of the Surviving Corporation. I-32 Section 5.6 Indemnification. (a) From and after the Effective Time, the Surviving Corporation will indemnify, defend and hold harmless the officers, directors and employees of Company and its Subsidiaries who were such at any time prior to the Effective Time (the "Indemnified Parties") from and against all losses, expenses, claims, damages or liabilities arising out of the transactions contemplated by this Agreement to the fullest extent permitted or required under applicable law, and the Indemnified Parties will be advanced expenses subject to a customary reimbursement agreement. All rights to indemnification existing in favor of the directors, officers or employees of Company and its Subsidiaries as provided in Company's Second Amended and Restated Articles of Incorporation or Amended and Restated Bylaws, as in effect as of the date of this Agreement, with respect to matters occurring through the Effective Time, will survive the Merger and will continue in full force and effect thereafter. Parent will maintain in effect for not less than six years after the Effective Time the current policies of directors' and officers' liability insurance maintained by Company, and will cause the Surviving Corporation to indemnify the Indemnified Parties, from and against all losses, expenses, claims, damages or liabilities arising from or related to matters, acts or omissions occurring on or prior to the Effective Time; provided, however, that Parent may substitute therefor policies of at least the same coverage (with carriers comparable to Company's existing carriers) containing terms and conditions which are no less advantageous to the Indemnified Parties; and provided, further, that Parent will not be required in order to maintain or procure such coverage to pay an annual premium in excess of 200% of the current annual premium paid by the Company for its existing coverage (the "Cap"); and provided, further, that if equivalent coverage cannot be obtained, or can be obtained only by paying an annual premium in excess of Cap, the Parent will only be required to obtain as much coverage as can be obtained by paying an annual premium equal to the Cap. (b) In the event that any action, suit, proceeding or investigation relating hereto or to the transactions contemplated by this Agreement is commenced, whether before or after the Effective Time, the parties hereto agree to cooperate and use their respective reasonable efforts to vigorously defend against and respond thereto. (c) Any Indemnified Party, upon learning of any claim, action, suit, proceeding or investigation for which such party may seek indemnification under this Section 5.6, will promptly notify Parent; provided that the failure to so promptly notify will not impede, limit or prohibit an Indemnified Party from recovering except to the extent a delay permanently prejudiced Parent's ability to defend such claim, action, suit, proceeding or investigation. In case any such action shall be brought against an Indemnified Party and it shall give written notice to Parent of the commencement thereof, Parent shall be entitled to participate therein and, to the extent that it may wish, to assume the defense thereof with counsel reasonably satisfactory to such Indemnified Party. If Parent elects to assume the defense of such action, the Indemnified Party shall have the right to employ separate counsel at its own expense and to participate in the defense thereof. If Parent elects not to assume (or fails to assume) the defense of such action, the Indemnified Party shall be entitled to assume the defense of such action with counsel of its own choice, at the expense of Parent. If the action is asserted against both Parent and the Indemnified Party and there is a conflict of interests which renders it inappropriate for the same counsel to represent both Parent and the Indemnified Party, Parent shall be responsible for paying for separate counsel for the Indemnified Party; provided, however, that if there is more than one Indemnified Party, Parent shall not be responsible for paying for more than one separate firm of attorneys (and any local counsel) to represent the indemnified parties, regardless of the number of indemnified parties. If Parent elects to assume the defense of such action, (i) no compromise or settlement thereof may be effected by Parent without the Indemnified Party's written consent (which shall not be unreasonably withheld) and (ii) the Indemnified Party shall have no liability with respect to any compromise or settlement thereof effected without its written consent (which shall not be unreasonably withheld). Section 5.7 Additional Agreements. (a) Subject to the terms and conditions herein provided, each of the parties hereto agrees diligently to use their best efforts to take, or cause to be taken, all actions and to do, or cause to be done, all things necessary, proper or advisable under applicable laws and regulations to consummate and make effective the transactions contemplated by this Agreement and the other Transaction Documents as soon as reasonably practical, including to (i) obtain all necessary waivers, consents and I-33 approvals, (ii) effect all necessary registrations and filings, (iii) lift any injunction to the Merger (and, in such case, to proceed with the Merger as expeditiously as possible), and (iv) otherwise promptly satisfy the conditions set forth in Article VI. In addition, Parent agrees to cooperate with Company in obtaining a legal opinion from Akin, Gump, Strauss, Hauer & Feld, LLP, counsel to Company, reasonably satisfactory to Company, to be delivered in connection with the filing of the Form S-4 concerning tax matters. In connection with each of such opinions of Akin, Gump, Strauss, Hauer & Feld, LLP, Parent and Company shall each deliver a certificate executed by an appropriate officer of Parent containing customary representations as to current financial matters. (b) Company will give prompt notice to Parent, and Parent or Merger Sub will give prompt notice to Company, of: (i) any notice or other communication from any Person alleging that the consent of such Person is or may be required in connection with the transactions contemplated by this Agreement; (ii) any notice or other communication from any Governmental Entity in connection with the transactions contemplated by the Transaction Documents; and (iii) any actions, suits, claims, investigations or proceedings commenced or, to Company's or Parent's Knowledge, as applicable, threatened against, relating to or involving or otherwise affecting it or any of its Subsidiaries which, if pending on the date of this Agreement would have been required to have been disclosed pursuant to Section 2.7, 2.8, 3.7 and 3.8 or which relate to the consummation of the transactions contemplated by this Agreement. (c) Parent and Merger Sub, on the one hand, and Company, on the other hand, will consult with each other before issuing, and provide each other the opportunity to review and comment upon, any press release or other public statements with respect to the transactions contemplated by this Agreement and the other Transaction Documents, including the Merger, and will not issue any such press release or make any such public statement prior to such consultation. (d) Parent agrees to cause its Board of Directors prior to the Effective Time to approve in the form required by Rule 16b-3 under the Exchange Act certain acquisitions of Parent Common Stock pursuant to the Merger, as directed by Company and in form reasonably acceptable to Company. (e) In case at any time after the Effective Time any further action is necessary or desirable to carry out the purposes of this Agreement and the other Transaction Documents, the proper officers and/or directors of Parent and Company will use their reasonable best efforts to take all such necessary action. Section 5.8 No Shop. Company agrees (a) that neither it nor any of its Subsidiaries or affiliates will, and it will direct and use commercially reasonable efforts to cause its officers, directors, employees, agents and representatives (including, without limitation, any investment banker, attorney or accountant retained by it or any of its Subsidiaries or affiliates) not to, initiate, solicit or encourage, directly or indirectly, any inquiries or the making or implementation of any proposal or offer (including, without limitation, any proposal or offer to its shareholders) with respect to a merger, acquisition, consolidation or similar transaction involving, or any purchase of all or any significant portion of the assets or equity securities covering all or any significant portion of the assets of, Company and its Subsidiaries, taken as a whole (any such proposal or offer being hereinafter referred to as an "Alternative Proposal"), or engage in any negotiations concerning, or provide any confidential information or data to, or have any discussions with, any person relating to an Alternative Proposal, or release any third party from any obligations under any existing standstill agreement or arrangement, or enter into any agreement with respect to an Alternative Proposal, or otherwise facilitate any effort or attempt to make or implement an Alternative Proposal; (b) that it will immediately cease and cause to be terminated any existing activities, discussions or negotiations with any parties with respect to any of the foregoing, and it will take the I-34 necessary steps to inform the individuals or entities referred to above of the obligations undertaken in this Section 5.9; and (c) that it will notify Parent immediately if any such inquiries or proposals are received by, any such information is requested from, or any such negotiations or discussions are sought to be initiated or continued with, it. Notwithstanding the foregoing, prior to the Effective Time, Company may, directly or indirectly, furnish information and access to, and may participate in discussions and negotiate with, any Person, if (i) such person has submitted an unsolicited proposal to the Board of Directors of Company relating to an Alternative Proposal, (ii) the Board of Directors of Company believes that such Alternative Proposal is superior from a financial point of view to the transactions contemplated by the Transaction Documents, and (iii) the Board of Directors of Company determines in its good faith judgment that it is required to take such action to comply with the Board of Directors' fiduciary duty imposed by law (a "Superior Proposal"). Such Board of Directors will provide a summary of any such proposal to Parent immediately after receipt thereof and thereafter keep Parent promptly advised of any development with respect thereto and any revision of the terms of such Superior Proposal. Section 5.9 Advice of Changes, SEC Filings. Company will confer on a regular basis with Parent on operational matters. Parent and Company will promptly advise each other of any change or event that has had, or could reasonably be expected to have, a Company Material Adverse Effect or a Parent Material Adverse Effect, as the case may be.

Upon such termination, Parent, Merger Sub and their respective Subsidiaries will be deemed to have waived any and all claims Parent and its Subsidiaries may have at law or in equity against Company, its Subsidiaries or their respective officers, directors or employees arising out of or relating to this Agreement or the other Transaction Documents. Section 7.2 Effect of Termination. (a) In the event of termination of this Agreement by either Parent or Company as provided in Section 7.1, this Agreement will forthwith become void and there will be no liability hereunder on the part of Company, Parent or their respective officers or directors; provided, however, that nothing contained in this Section 7.2 will relieve any party hereto from any liability for any willful breach of a representation or warranty contained in this Agreement, for the breach of any covenant or agreement contained in this Agreement or under Section 7.1(d), this Section 7.2 and Article VIII. (b) If Company terminates this Agreement pursuant to Section 7.1(d), forthwith upon such termination Company will pay Parent $2,350,000 in immediately available funds.

Each of Parent and Company acknowledges that the agreements contained in this Section 7.2(c) are an integral part of the transactions contemplated in this Agreement, and that, without these agreements, Parent and Company would not enter into this Agreement; accordingly, if the breaching party falls to promptly pay the amount due pursuant to this Section 7.2(c), and, in order to obtain such payment, the non-breaching party commences a suit which results in a judgment for the Expenses Fee, the breaching party will pay to the non-breaching party its costs and expenses (including attorney's fees) in connection with such suit. (d) If the Merger does not occur for any reason other than (i) a breach by Company of its representations, warranties, covenants or agreements set forth in this Agreement resulting in the condition set forth in Section 6.3(a) not being satisfied, (ii) any of the conditions set forth in Sections 6.1(e), 6.2(c), 6.3(b) and 6.3(c) not being satisfied, or (iii) a termination of this Agreement by Parent under Section 7.1(h), Parent will promptly pay $250,000 in immediately available funds to Company, which amount is intended to reimburse Company for its costs and expenses incurred in connection with this Agreement and the transactions contemplated by the Transaction Documents.

This Agreement may be amended by the parties hereto, by or pursuant to action taken by their respective Boards of Directors, at any time before or after approval of the matters presented in connection with the Merger by the shareholders of Company, Parent and Merger Sub, but, after any such approval no amendment will be made which by law requires further approval by such shareholders without such further approval. This Agreement may not be amended except by an instrument in writing duly executed by each of the parties hereto. I-39 Section 7.4 Waiver.

Any agreement on the part of a party hereto to any such extension or waiver will be valid only if set forth in an instrument in writing duly executed by such party.

Each Shareholder hereby agrees that, during the term of this Agreement, at any meeting of the shareholders of Company, however called, and in any action by written consent of the shareholders of Company, it will (a) attend any such meeting, in person or by proxy, (b) vote all voting Equity Securities, whether now owned or hereafter acquired, of such Shareholder in favor of the Merger; (c) not vote any voting Equity Securities, whether now owned or hereafter acquired, in favor of any action or agreement which would result in a breach in any material respect of any material covenant, representation or warranty or any other obligation of Company under the Merger Agreement; and (d) vote all voting Equity Securities, whether now owned or hereafter acquired, of such Shareholder against any action or agreement the primary or a substantial purpose of which would be to materially impede, interfere with or attempt to discourage the Merger, including, but not limited to: (i) any change in the management or board of directors of Company, except to fill vacancies occurring after the date of this Agreement or as otherwise agreed to in writing by Parent; (ii) except as expressly contemplated by the Transaction Documents, any material change in the present capitalization or dividend policy of Company; or (iii) except as expressly contemplated by the Transaction Documents, any other material change in Company's corporate structure or business. 5. Registration Rights. Parent will use reasonable efforts to prepare and file a shelf registration statement (the "Registration Statement") pursuant to Rule 415 under the Securities Act to permit the sale or other disposition of any or all shares of Parent Common Stock received by each Shareholder in the Merger, in V-2 accordance with the intended method of sale or other disposition elected by such Shareholder, and Parent will use its best efforts to qualify such shares of Parent Common Stock under any applicable state securities laws. Parent will use all reasonable efforts (i) to cause the Registration Statement to become effective on or before the Effective Time, (ii) to obtain all consents or waivers of other parties which are required therefor, and (iii) to keep the Registration Statement continuously effective in order to permit the prospectus forming part thereof to be usable by such Shareholder for a period ending two years from the Effective Time, or for such shorter period that will terminate when all shares of Parent Common Stock covered by the Registration Statement have been sold pursuant to the Registration Statement or otherwise cease to be outstanding. The offer and sale under the Registration Statement or the obligation of Parent to file the Registration Statement and to maintain its effectiveness may be suspended for one or more periods of time not exceeding 90 calendar days in the aggregate with respect to such Registration Statement if the Board of Directors of Parent will have determined in good faith that the offering and sales under the Registration Statement, the filing of such Registration Statement or the maintenance of its effectiveness would require disclosure of or would interfere in any material respect with any material financing, acquisition, merger or other transaction involving Parent or any of its Subsidiaries or would otherwise require disclosure of nonpublic information that would materially and adversely affect Parent. The Registration Statement prepared and filed under this Section, and any sale covered thereby, will be at Parent's expense except for underwriting discounts or commissions, brokers' fees and the fees and disbursements of each Shareholder's counsel related thereto. Each Shareholder will provide all information reasonably requested by Parent for inclusion in the Registration Statement to be filed hereunder. In connection with the registration pursuant to this Section, each Shareholder and Parent will provide each other and any underwriter of the offering with customary representations, warranties, covenants, and rights to indemnification and contribution. 6. Stock Elections. Each Shareholder agrees that unless it has effectively made a Stock Election pursuant to Section 1.6 of the Merger Agreement prior to the filing with the Commission by Company and Parent of the Joint Proxy Statement/Prospectus, it will be deemed to have failed to make, and will not be eligible to make, a Stock Election with respect to the Shares or shares of Company Common Stock issuable upon the exercise of the Options and Warrants under the Merger Agreement. 7. Additional Agreements. If a Shareholder makes a Stock Election and, as a result of the application of Section 1.5(e) of the Merger Agreement, a portion of such Shareholder's Stock Election Shares (the "Converted Stock Election Shares") are converted into the right to receive the Cash Consideration in the Merger, then immediately after the Effective Time, such Shareholder agrees to buy, and Parent agrees to issue and deliver to such Shareholder, the number for shares of PetroCorp Common Stock which is equal to (a) the Cash Consideration which is payable pursuant to the Merger with respect to the Converted Stock Election Shares, divided by (b) the Per Share Merger Consideration. 8. Further Assurances. Each party hereto will perform such further acts and execute such further documents as may reasonably be required to carry out the provisions of this Agreement. 9. Remedies. The parties agree that legal remedies for breach of this Agreement will be inadequate and that this Agreement may be enforced by either party by injunctive or other equitable relief. 10. Notices.

The undersigned has been further advised that pursuant to the terms of the Agreement and Plan of Merger dated as of December 22, 2000 (the "Merger Agreement") among Company, PetroCorp Acquisition Company, a Delaware corporation ("Merger Sub"), and PetroCorp Incorporated, a Texas corporation ("Parent"), Company will be merged with and into Merger Sub (the "Merger") and that as a result of the Merger, the undersigned may receive shares of Parent Common Stock in exchange for shares of Company Common Stock owned by the undersigned. Capitalized terms used but not defined herein will have the meanings given them in the Merger Agreement. 1. The undersigned represents, warrants and covenants to Parent that in the event the undersigned receives any Parent Common Stock pursuant to the Merger (the "Parent Merger Shares"), the undersigned: A. Shall not make any sale, transfer or other disposition of the Parent Merger Shares in violation of the Act or the Rules and Regulations. B. Has read carefully this letter and discussed applicable limitations upon the ability of the undersigned to sell, transfer or otherwise dispose of Parent Merger Shares to the extent the undersigned believed necessary with counsel of the undersigned or counsel for Company. C. Unless the undersigned has executed a Company Shareholder Agreement and the Commission objects to registration of the Parent Merger Shares, has been advised that the issuance of the Parent Merger Shares to the undersigned will be registered with the Commission under the Act on a Registration Statement on Form S-4. However, the undersigned has also been advised that, since at the time of the approval of the Merger by written consent of the stockholders of Parent, the undersigned may be deemed to have been an affiliate of Company and the distribution by the undersigned of the Parent Merger Shares has not been registered under the Act, the undersigned may be prohibited from selling, transferring or otherwise disposing of the Parent Merger Shares unless (i) such sale, transfer or other disposition has been registered under the Act, (ii) such sale, transfer or other disposition is made in conformity with the volume and other limitations of Rule 145 promulgated by the Commission under the Act, or (iii) in the opinion of counsel reasonably acceptable to Parent, such sale, transfer or other disposition is otherwise exempt from registration under the Act. D. Understands that, except as provided in paragraph 2 below, Parent is under no obligation to register the sale, transfer or other disposition of the Parent Merger Shares by the undersigned or on behalf of the undersigned under the Act or (except as forth in paragraph 2 below) to take any other action necessary in order to make compliance with an exemption from such registration available. E. Also understands that, unless a registration statement permitting the sale or other disposition of any or all of the Parent Merger Shares is effective, Parent may give stop transfer instructions to Parent's transfer agent with respect to the Parent Merger Shares and that Parent reserves the right to place on the certificates for the Parent Merger Shares, or any substitutions therefor, a legend stating in substance: VII-1 "The securities represented by this certificate have been issued in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies and may only be sold or otherwise transferred in compliance with the requirements of Rule 145 or pursuant to a registration statement under said Act or an exemption from such registration." F. Also understands that unless the transfer by the undersigned of the Parent Merger Shares has been registered under the Act or is a sale made in conformity with the provisions of Rule 145, Parent reserves the right to put the following legend on the certificates issued to transferees of the undersigned: "The securities represented by this certificate have not been registered under the Securities Act of 1933 and were acquired from a person who received such shares in a transaction to which Rule 145 promulgated under the Securities Act of 1933 applies. The securities have been acquired by the holder not with a view to, or for resale in connection with, any distribution thereof within the meaning of Securities Act of 1933 and may not be sold, pledged or otherwise transferred except in accordance with an exemption from the registration requirements of the Securities Act of 1933." G. Execution of this letter should not be considered an admission on the part of the undersigned that the undersigned is an affiliate of Company as described in the first paragraph of this letter, nor as a waiver of any rights the undersigned may have to object to any claim that the undersigned is such an affiliate on or after the date of this letter. 2. By Parent's acceptance of this letter, Parent hereby agrees with the undersigned as follows: A. For so long as and to the extent necessary to permit the undersigned to sell the Parent Merger Shares pursuant to Rule 145 and, to the extent applicable, Rule 144 under the Act, Parent shall (a) use its reasonable best efforts to (i) file, on a timely basis, all reports and data required to be filed with the Commission by it pursuant to Section 13 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and (ii) furnish to the undersigned upon request a written statement as to whether Parent has complied with such reporting requirements during the 12 months preceding any proposed sale of the Parent Merger Shares by the undersigned under Rule 145, and (b) otherwise use its reasonable efforts to permit such sales pursuant to Rule 145 and Rule 144. Parent has filed all reports required to be filed with the Commission under Section 13 of the Exchange Act during the preceding 12 months. B. It is understood and agreed that certificates with any legends set forth in paragraphs E and F above will be substituted by delivery of certificates without such legend if (i) one year shall have elapsed from the date the undersigned acquired the Parent Merger Shares and the provisions of Rule 145(d)(2) are then available to the undersigned, (ii) two years shall have elapsed from the date the undersigned acquired the Parent Merger Shares and the provisions of Rule 145(d)(3) are then applicable to the undersigned, or (iii) Parent has received either an opinion of counsel, which opinion and counsel shall be reasonably satisfactory to Parent, or a "no-action" letter obtained by the undersigned from the staff of the Commission, to the effect that the restrictions imposed by Rule 144 and Rule 145 under the Act no longer apply to the undersigned. C. Parent will use reasonable efforts to prepare and file a shelf registration statement (the "Registration Statement") pursuant to Rule 415 under the Act to permit the sale or other disposition of any or all of the Parent Merger Shares in accordance with the intended method of sale or other disposition elected by the undersigned, and Parent will use its best efforts to qualify such shares of Parent Merger Shares under any applicable state securities laws.

The Merger Agreement provides for, among other things, the merger of Southern Mineral with and into PetroCorp Sub (the "Merger"). Upon consummation of the Merger, each outstanding share of common stock, par value $.01 per share, of Southern Mineral (the "Southern Mineral Common Stock") (other than Southern Mineral Common Stock held by Southern Mineral as treasury stock or owned by PetroCorp or any subsidiary of PetroCorp or as to which dissenters' rights have been perfected) will be converted into the right to receive (i) $4.71 per share in cash subject to adjustment as described in the Merger Agreement or (ii) at the election of each holder of Southern Mineral Common Stock in accordance with the Merger Agreement, a number of shares of common stock, par value $.01 per share, of PetroCorp (the "PetroCorp Common Stock") equal to the Exchange Ratio (as defined in the Merger Agreement) (subject to limitation on such election set forth in the Merger Agreement if holders of Southern Mineral Common Stock elect to receive more than an aggregate of 4,000,000 shares of PetroCorp Common Stock) (the "Transaction Consideration"). You have requested our opinion as to whether the Transaction Consideration is fair from a financial point of view to the holders of Southern Mineral Common Stock. In arriving at our opinion, we have, among other things: 1. reviewed certain publicly available business and financial information relating to PetroCorp and Southern Mineral, including (a) Annual Reports on Form 10-K and related audited financial statements for the fiscal years ended December 31, 1998 and December 31, 1999, and (b) the Quarterly Reports on Form 10-Q and related unaudited financial statements for the fiscal quarters ended March 31, 2000, June 30, 2000 and September 30, 2000; 2. reviewed a draft, dated March 6, 2001, of the Annual Report on Form 10-K for the fiscal year ended December 31, 2000 of Southern Mineral and a draft, dated March 6, 2001, of the Annual Report on Form 10-K for the fiscal year ended December 31, 2000 of PetroCorp; 3. reviewed certain estimates of Southern Mineral's reserves, including (a) estimates of proved and probable oil and gas reserves prepared by Netherland, Sewell & Associates, Inc. (as to United States and Ecuador reserves only) as of December 31, 2000 and (b) estimates of proved and probable oil and gas reserves prepared by Chapman Petroleum Engineering Ltd. (as to Canadian reserves only) as of December 31, 2000; 4. reviewed certain estimates of PetroCorp's reserves, including estimates of proved and probable oil and gas reserves prepared by Huddleston & Co., Inc. as of December 31, 2000; 5. analyzed certain historical and projected financial and operating data (i) of PetroCorp prepared by the management and staff of PetroCorp and (ii) of Southern Mineral prepared in conjunction with, and approved by, the management and staff of Southern Mineral; VIII-1 6. discussed the current and projected operations and prospects of PetroCorp and Southern Mineral with the management and staff of PetroCorp and Southern Mineral, respectively; 7. reviewed the trading history of PetroCorp Common Stock and Southern Mineral Common Stock; 8. compared recent stock market capitalization indicators for PetroCorp and Southern Mineral with recent stock market capitalization indicators for certain other publicly-traded independent energy companies; 9. compared the financial terms of the Merger with the financial terms of certain other transactions that we deemed to be relevant; 10. participated in certain discussions and negotiations among the representatives of Southern Mineral, PetroCorp and their financial and legal advisors; 11. reviewed the Merger Agreement; 12. reviewed a draft dated March 7, 2001 of the Amendment; and 13. reviewed such other financial studies and analyses and performed such other investigations and took into account such other matters as we have deemed necessary or appropriate. In preparing our opinion, we have assumed and relied upon, without assuming any responsibility for, or independently verifying, the accuracy and completeness of any information supplied or otherwise made available to us by Southern Mineral and PetroCorp. We have further relied upon the assurances of the management of Southern Mineral and PetroCorp that they are unaware of any facts that would make the information provided to us incomplete or misleading in any material respect. With respect to projected financial and operating data, we have assumed that they have been reasonably prepared on bases reflecting the best currently available estimates and judgments of the managements and staff of Southern Mineral and PetroCorp, respectively, relating to the future financial and operational performance of each company. With respect to the estimates of oil and gas reserves, we have assumed that they have been reasonably prepared on bases reflecting the best available estimates and judgments of the managements and staff of Southern Mineral or PetroCorp or their respective engineering consultants relating to the oil and gas properties of Southern Mineral and PetroCorp, respectively. We have not made an independent evaluation or appraisal of the assets or liabilities of Southern Mineral or PetroCorp nor, except for the estimates of oil and gas reserves referred to above, have we been furnished with such an evaluation or appraisal. In addition, we have not assumed any obligation to conduct, nor have we conducted, any physical inspection of the properties or facilities of Southern Mineral or PetroCorp. We have assumed, based on discussions with the management and staff of Southern Mineral, that no adjustment to the Transaction Consideration will be required under the Merger Agreement on the basis of the transaction costs incurred by Southern Mineral. We have also assumed that the final form of the Amendment will be substantially similar to the last draft of the Amendment reviewed by us. Our opinion relates solely to the fairness, from a financial point of view, of the Transaction Consideration to the holders of Southern Mineral Common Stock. This opinion is for the use and benefit of the Board of Directors of Southern Mineral and does not constitute a recommendation to any holder of Southern Mineral Common Stock as to how such stockholder should vote on the Merger. We have not been asked to consider, and this opinion does not address, the after-tax consequences of the Merger to any particular stockholder of Southern Mineral or the price at which PetroCorp Common Stock will actually trade following the announcement or consummation of the Merger. As you are aware, we have acted as financial advisor to Southern Mineral and we will receive a fee from Southern Mineral for such services, which is contingent upon the consummation of the Merger. In addition, Southern Mineral has agreed to indemnify us for certain liabilities arising out of our engagement. We have, in the past, provided financial advisory services to Southern Mineral and have received customary fees for such services. In addition, in the ordinary course of business, we or our affiliates may trade in the debt or equity securities of Southern Mineral or PetroCorp for the accounts of our customers or for our own account and, accordingly, may at any time hold a long or short position in such securities. VIII-2 Our opinion is rendered on the basis of conditions in the securities markets and the oil and gas markets prevailing as of the date hereof and the condition and prospects, financial and otherwise, of PetroCorp and Southern Mineral as they have been represented to us as of the date hereof or as they were reflected in the materials and discussions described above. Based upon and subject to the foregoing, it is our opinion that, as of the date hereof, the Transaction Consideration is fair from a financial point of view to the holders of Southern Mineral Common Stock. Very truly yours, /s/ Petrie Parkman & Co. _____________________________________ PETRIE PARKMAN & CO., INC. VIII-3 ANNEX IX NEVADA REVISED STATUTES TITLE 7.

A subject corporation shall commence the proceeding in the district court of the county where its registered office is located. If the subject corporation is a foreign entity without a resident agent in the state, it shall commence the proceeding in the county where the registered office of the domestic corporation merged with or whose shares were acquired by the foreign entity was located. 3. The subject corporation shall make all dissenters, whether or not residents of Nevada, whose demands remain unsettled, parties to the proceeding as in an action against their shares. All parties must be served with a copy of the petition. Nonresidents may be served by registered or certified mail or by publication as provided by law. 4.

IX-5 NRS 92A.500 Legal proceeding to determine fair value: Assessment of costs and fees. 1. The court in a proceeding to determine fair value shall determine all of the costs of the proceeding, including the reasonable compensation and expenses of any appraisers appointed by the court. The court shall assess the costs against the subject corporation, except that the court may assess costs against all or some of the dissenters, in amounts the court finds equitable, to the extent the court finds the dissenters acted arbitrarily, vexatiously or not in good faith in demanding payment. 2. The court may also assess the fees and expenses of the counsel and experts for the respective parties, in amounts the court finds equitable: (a) Against the subject corporation and in favor of all dissenters if the court finds the subject corporation did not substantially comply with the requirements of NRS 92A.300 to 92A.500, inclusive; or (b) Against either the subject corporation or a dissenter in favor of any other party, if the court finds that the party against whom the fees and expenses are assessed acted arbitrarily, vexatiously or not in good faith with respect to the rights provided by NRS 92A.300 to 92A.500, inclusive. 3. If the court finds that the services of counsel for any dissenter were of substantial benefit to other dissenters similarly situated, and that the fees for those services should not be assessed against the subject corporation, the court may award to those counsel reasonable fees to be paid out of the amounts awarded to the dissenters who were benefited. 4. In a proceeding commenced pursuant to NRS 92A.460, the court may assess the costs against the subject corporation, except that the court may assess costs against all or some of the dissenters who are parties to the proceeding, in amounts the court finds equitable, to the extent the court finds that such parties did not act in good faith in instituting the proceeding. 5.

IX-6 ANNEX X SERIES B PERPETUAL WARRANT AGREEMENT This Series B Perpetual Warrant Agreement (as amended, restated or otherwise modified from time to time, this "AGREEMENT") is made as of September 29, 2000, between Southern Mineral Corporation, a Nevada corporation (including its successors and permitted assigns, the "COMPANY"), and American Stock Transfer & Trust Company, a New York corporation (including its successors and permitted assigns, the "WARRANT AGENT"). WHEREAS, the Company has determined to issue and deliver Series B Perpetual Warrant Certificates ("WARRANT CERTIFICATES") initially in the form of Exhibit A, representing Series B Perpetual Warrants ("WARRANTS"), to the persons and in the amounts listed on Exhibit B; WHEREAS, each Warrant represented on a Warrant Certificate entitles the holder thereof to purchase one share (as adjusted) of common stock, par value $0.01 per share ("COMMON STOCK"), of the Company for each such Warrant exercised; WHEREAS, the Company desires to provide for the form and provisions of the Warrant Certificates, the terms upon which they shall be issued and exercised, and the respective rights, limitation of rights, and immunities of the Company, the Warrant Agent, and the bearers of the Warrants Certificates; and WHEREAS, all acts and things necessary to make the Warrant Certificates when executed on behalf of the Company and countersigned by or on behalf of the Warrant Agent, as provided in this agreement, the valid, binding, and legal obligations of the Company, and to authorize the execution and delivery of this Agreement, have been done and performed. NOW, THEREFORE, in consideration of the mutual agreements herein contained, the parties hereto agree as follows: ARTICLE I EXECUTION AND COUNTERSIGNATURE OF WARRANT CERTIFICATES Section 1.1. Execution and countersignature of Warrant Certificates. (a) Each Warrant Certificate, whenever issued, shall be dated August 1, 2000, shall be substantially in the form of Exhibit A and may have such legends and endorsements typed, stamped, printed, lithographed or engraved thereon as the Company may deem appropriate and as are not inconsistent with the provisions of this Agreement, or as may be required to comply with any law or with any rule or regulation pursuant thereto or with any rule or regulation of any securities exchange on which the Warrant Certificates may be listed, or to conform to customary usage. Each Warrant Certificate shall be signed by, or bear the facsimile signature of, the President or a Vice President of the Company and shall bear a facsimile of the Company's seal. In case any officer whose facsimile signature has been placed upon any Warrant Certificate shall have ceased to hold such office before such Warrant Certificate is issued, such Warrant Certificate may be issued with the same effect as if such officer had held such office at the date of issuance. No Warrant Certificate may be exercised until it has been countersigned by the Warrant Agent as provided in Section 1.1(b). (b) The Warrant Agent shall countersign a Warrant Certificate only: (i) if the Warrant Certificate is to be issued in exchange or substitution for one or more previously countersigned Warrant Certificates, as hereinafter provided, or (ii) if the Company instructs the Warrant Agent to do so. X-1 (c) Unless and until countersigned by the Warrant Agent pursuant to this Agreement, a Warrant Certificate shall be invalid and of no effect. ARTICLE II WARRANT PRICE, DURATION AND EXERCISE OF WARRANT CERTIFICATES Section 2.1. Warrant Price. Each Warrant shall, when the Warrant Certificate by which such Warrant is represented is countersigned by the Warrant Agent, entitle the holder thereof, subject to the provisions thereof and of this Agreement, to purchase from the Company one share of Common Stock at the price of $4.21 per share, subject to adjustment as provided in Article III. The term "WARRANT PRICE" as used in this Agreement refers to the price per share at which Common Stock may be purchased at the time a Warrant is exercised. Section 2.2. Perpetual Duration of Warrants. The Warrants are perpetual; that is, the Warrants will not expire. Section 2.3. Exercise of Warrants. (a) A Warrant, when the Warrant Certificate by which such Warrant is represented is countersigned by the Warrant Agent, may be exercised in whole or part, at any time of from time to time, by surrendering such Warrant Certificate at the corporate trust office of the Warrant Agent in New York, with the subscription form set forth in the Warrant Certificate duly executed, and by paying in full, in lawful money of the United States, the Warrant Price for each full share of Common Stock as to which such Warrant is exercised and any applicable taxes. (b) As soon as practicable after the exercise of any Warrant, the Company shall issue to or to the order of the holder of such Warrant a certificate or certificates for the number of whole shares of Common Stock to which such holder is entitled, registered in such name or names as may be directed by such holder, and, if such Warrant shall not have been exercised in full (except with respect to a remaining fraction of a share), a new countersigned Warrant Certificate for the number of Warrants represented by such holder's previous Warrant Certificate which shall not have been exercised. In the event that the holder of one or more Warrants exercising his purchase rights thereunder has pursuant to such exercise the right to purchase a fraction of a share of Common Stock, the Company shall, in lieu of issuing to such holder a fractional share, pay such holder cash in an amount equal to: (i) (x) the fraction to which such holder is entitled multiplied by (y) the closing market price of a share of Common Stock on the business day immediately following the day of exercise minus (ii) (x) the same fraction multiplied by (y) the Warrant Price on such day. If no sale takes place on such day, the closing market price for such day shall be deemed to be (i) the average of the closing bid and asked prices on such day, as officially quoted, as reported in the principal reporting system with respect to securities listed on the principal national securities exchange or market on which the Common Stock is listed or admitted to trading or, if the Common Stock is not listed or admitted to trading on any national securities exchange or market, the last quoted price or, if not so quoted, the average of the high bid and low asked prices in the over-the-counter market, as reported by NASDAQ or such other system then in use or, if on any such date the Common Stock is not quoted by any such organization, the average of the closing bid and asked prices as furnished by a professional market maker making a market in the Common Stock selected by the Board of Directors of the Company or, if on such day no such market maker is making a market in the Common Stock, the fair value of the Common Stock on such date as determined in good faith by the Board of Directors of the Company. (c) All shares of Common Stock issued upon the exercise of a Warrant shall be validly issued, and the Company shall pay all taxes in respect of the issue thereof.

(d) Each person (or entity) in whose name any such certificate for shares of Common Stock is issued shall for all purposes be deemed to have become the holder of record of such shares on the date on which the Warrant Certificate was surrendered and payment of the Warrant Price and any applicable taxes was made, irrespective of the date of delivery of such certificate, except that, if the date of such surrender and payment is a date when the stock transfer books of the Company are closed, such person shall be deemed to have become the holder of such shares at the close of business on the next succeeding date on which the Company's stock transfer books are open.

If after the date hereof any capital reorganization or reclassification of the Common Stock of the Company, or any consolidation, merger, share exchange or similar transaction involving the Company, or the sale of all or substantially all of the Company's assets shall be effected, then, as a condition of such reorganization, reclassification, consolidation, merger, share exchange, similar transaction or asset sale, lawful and fair provision shall be made whereby the Warrant Certificate holders shall thereafter have the right to purchase and receive upon the basis and upon the terms and conditions specified in the Warrant Certificates and in lieu of the shares of Common Stock of the Company immediately theretofore purchasable and receivable upon the exercise of the Warrants represented thereby, such shares of stock, securities, or assets as may be issued or payable with respect to or in exchange for a number of outstanding shares of such Common Stock equal to the number of shares of such stock immediately theretofore purchasable and receivable upon the exercise of the Warrants had such reorganization, reclassification, consolidation, merger, share exchange, similar transaction or asset sale not taken place, and in any such case appropriate provision shall be made with respect to the rights and interests of the Warrant Certificate holders to the end that the provisions hereof (including, without limitation, provisions for adjustments of the Warrant Price and of the number of shares purchasable upon the exercise of the Warrants) shall thereafter be applicable, as nearly as may be in relation to any share of stock, securities, or assets thereafter deliverable upon the exercise hereof. The Company shall not effect any such consolidation, merger, share exchange, similar transaction or sale unless prior to the consummation thereof the successor entity (if other than the Company) resulting from such transaction, or the entity purchasing such assets, shall assume by written instrument executed and X-3 delivered to the Warrant Agent the obligation to deliver to the Warrant Certificate holders such shares of stock, securities, or assets as, in accordance with the foregoing provisions, such holders may be entitled to purchase.

Upon any adjustment of the Warrant Price or the number of shares issuable on exercise of a Warrant, then and in each such case the Company shall promptly give written notice thereof to the Warrant Agent, which notice shall state the Warrant Price resulting from any such adjustment and the increase or decrease, if any, in the number of shares purchasable at such price upon the exercise of a Warrant, setting forth in reasonable detail the method of calculation and the facts upon which such calculation is based. The Company shall also mail such notice to the addresses of the Warrant Certificate holders reflected in the records of the Warrant Agent.

Such notice shall also specify the date as of which the holders of record of Common Stock shall participate in such dividend, distribution, or subscription rights, or shall be entitled to exchange their Common Stock for securities or other property deliverable upon such reorganization, reclassification, consolidation, merger, sale, dissolution, liquidation, or winding up, as the case may be. Such notice shall be given and published at least 20 days prior to the action in question and not less than 20 days prior to the record date or the date on which the Company's transfer books are closed in respect thereto. Failure to give or publish such notice, or any defect therein, shall not affect the legality or validity of any of the matters set forth in the foregoing clauses (a) to (d), both inclusive.

Notwithstanding anything to the contrary in Section 3.1 or 3.2, upon exercise of any Warrant, cumulative adjustments in the number of shares issuable upon exercise of Warrants shall be made only to the nearest multiple of one-tenth of a share, i.e., fractions of less than five-hundredths of a share shall be disregarded and fractions of five- hundredths of a share or more shall be treated as being one-tenth of a share. Section 3.7. Form of Warrant Certificate. The form of Warrant Certificate need not be changed because of any change pursuant to this Article III, and Warrant Certificates issued after such change may state the same Warrant Price and the same number of shares as is stated in the Warrant Certificates initially issued pursuant to this Agreement. The Company may at any time in its sole discretion (which shall be conclusive) make any change in the form of Warrant Certificate that the Company may deem appropriate and that does not affect the substance thereof; and any Warrant Certificate thereafter issued or countersigned, whether in exchange or substitution for an outstanding Warrant Certificate or otherwise, may be in the form as so changed.

No Warrant Certificate holder, as such, shall be entitled to vote or to receive dividends or shall otherwise be deemed to be the holder of shares of Common Stock for any purpose, nor shall anything contained herein or in any Warrant Certificate be construed to confer upon any Warrant Certificate holder, as such, any of the rights of a stockholder of the Company or any right to vote upon or withhold consent to any action of the Company (whether upon any reorganization, issuance of securities, reclassification or conversion of Common Stock, consolidation, merger, share exchange or similar transaction, sale, lease, conveyance or otherwise), receive notice of meetings or other action affecting stockholders (except for notices expressly provided for in this Agreement) or receive dividends or subscription rights. Section 4.2. Lost, Stolen, Mutilated, or Destroyed Warrant Certificates.

Any such new Warrant Certificate shall constitute an original contractual obligation of the Company, whether or not the allegedly lost, stolen, mutilated, or destroyed Warrant Certificate shall be at any time enforceable by anyone. Section 4.3. Reservation of Common Stock. The Company shall at all times reserve and keep available a number of its authorized but unissued shares of Common Stock that will be sufficient to permit the exercise in full of all outstanding Warrants.

XI-i PART I Item 1. Business. General PetroCorp Incorporated is an independent energy company engaged in the acquisition, exploration and development of oil and gas properties, and in the production of oil, natural gas liquids and natural gas in North America. The Company's activities are conducted principally in the states of Oklahoma, Texas, Mississippi, Louisiana and Kansas, and in the province of Alberta, Canada. At December 31, 2000, the Company's proved reserves totaled 4.2 MMBbls of oil and 75.3 Bcf of natural gas and had an estimated pretax present value of future net revenues (PV-10) of $410.3 million. On a Mcfe basis, approximately 75% of the Company's proved reserves were natural gas at such date. In addition, the Company has unproved interest holdings with a net book value of $2.0 million, as well as interests in natural gas processing and gathering facilities with a net book value of $2.5 million. The Company was formed in July 1983 as a Delaware corporation and in December 1986 contributed its assets to a newly formed Texas general partnership. In October 1992, the Company changed its legal form from a Texas general partnership to a Texas corporation. In August 1999, the Company signed a Management Agreement with its largest shareholder, Kaiser-Francis Oil Company (Kaiser-Francis), under which Kaiser-Francis will provide management, technical and administrative support for all of the Company's operations in the United States and Canada. At that time, Gary R. Christopher was named President and CEO of the Company. Mr. Christopher is an employee of Kaiser-Francis Oil Company and has served on PetroCorp's Board of Directors since 1996. This Management Agreement was approved by the shareholders of the Company in October 1999 and took effect on November 1, 1999. A new slate of corporate officers was approved at that time. PetroCorp's principal executive offices are located at 6733 South Yale Avenue, Tulsa, Oklahoma 74136, with a mailing address of P.O. Box 21298, Tulsa, Oklahoma 74121-1298, and its telephone number is (918) 491- 4500. Unless the context otherwise requires, the terms the "Company" and "PetroCorp" refer to and include PetroCorp Incorporated, its predecessor entities (including the original Delaware corporation and the subsequent Texas general partnership) and all subsidiaries in which PetroCorp owns a 50% or greater interest. Business Strategy PetroCorp and its wholly-owned Canadian subsidiaries acquire, explore and develop oil and natural gas properties in North America. Acquisition Strategy. The Company has grown, in large part, through the acquisition of producing oil and gas properties. The Company generally focuses on acquisitions of long-lived natural gas reserves, located onshore in North America, and prefers acquisitions that provide additional potential through development or exploitation efforts, as well as exploratory drilling opportunities. Exploration and Development Strategy. Exploration and development activities are an important component of PetroCorp's business strategy. Through its Management Agreement with Kaiser-Francis, the Company will be able to allocate a greater portion of future cash flows to exploration and development activities. Exploration and Development Activities Pending Merger. On December 22, 2000, PetroCorp and Southern Mineral Corporation (Southern Mineral) executed a definitive agreement whereby Southern Mineral would be merged into PetroCorp. In the merger, shareholders of Southern Mineral will receive consideration of $4.71 per share in cash or, at their election, PetroCorp common stock or a combination of cash and stock, subject to certain adjustments. For both companies, the merger provides strategic and economic benefits. The operations of the two companies are very complementary, with PetroCorp primarily operating in the onshore Gulf Coast and Mid-continent areas of the United States and Southern Mineral primarily operating in the onshore Gulf Coast area of the United States. XI-1 PetroCorp and Southern Mineral both have significant oil and gas interests in the province of Alberta, Canada. Additionally, the combined company will benefit by having a substantially greater critical mass and the cost savings resulting from the consolidation of operations. PetroCorp will continue to operate under the Management Agreement with Kaiser-Francis Oil Company. PetroCorp and Southern Mineral have filed a preliminary joint proxy/registration statement with the Securities and Exchange Commission and, subject to receiving regulatory and shareholder approvals, anticipate a second quarter 2001 closing. United States. During 2000, the Company participated in three new discoveries in the Cement Field area, located in Caddo County, Oklahoma, increasing proved reserves by 317 MMcfe. In South Louisiana, PetroCorp participated in the successful Martin Heirs well in the Scott field area, adding 637 MMcfe of proved reserves. At year-end 2000, PetroCorp was participating in three deep prospects in the Mississippi Salt Basin in an area where several new field discoveries have recently been made. The North Smithtown Prospect was drilling toward a Smackover/Norphlet target at approximately 19,000 feet. The Northwest Clara Prospect seeks the same objectives at approximately 17,000 feet. The Company owns 7.5% and 10% working interests, respectively, in the two prospects. A third prospect in the same area is anticipated to spud after the completion of the Northwest Clara well. In South Texas, the Company plans to drill two prospect ideas as part of its Duval County joint venture with industry partners. Target objectives are Wilcox intervals between 10,000 and 16,000 feet. PetroCorp owns 17.5% working interest in this project. PetroCorp's most significant domestic project is the SW Oklahoma City Unit, which is showing positive response to water injection efforts. This is consistent with both the Company's initial estimates and offset field response in similar waterflood projects in the same region. Since the last half of 1999, the unit's production has more than doubled to over 400 barrels per day. Additional infill drilling is anticipated during 2001, which should lead to a projected peak waterflood response of between 800 and 1000 barrels per day by 2003. Canada. Recent activity in the Hanlan-Robb area has focused on the development of the Shaw, Basing and Redcap areas through the drilling of five new horizontal wells. Three of these wells have begun production and the other two are expected to be tied in to the Hanlan-Robb plant in the first quarter of 2001. Gross production increase, which is prior to royalty payments, from the addition of the three wells has added 34.5 MMcf/D and increased production from this area by 300% verses 1999 levels. Drilling is expected to continue in this area with up to 4 additional wells anticipated to be drilled in 2001. In the Banshee/Medicine Lodge area, PetroCorp completed a suspended well in an uphole zone which is currently producing 2 MMcf/D. At the Hanlan Swan Hills Gas Unit #1 additional compression was added in the south pool to protect the unit from a competing well outside the unit. Early in 2000, PetroCorp acquired the interest of a small owner in the unit to increase the Company's working interest to 7.6% of the unit. In the Minehead exploratory prospect, located ten miles east of the Hanlan- Robb Gas Plant, PetroCorp participated for a 4.7% working interest in a well targeting the Swan Hills formation. Although the well was unsuccessful in the Swan Hills, several up hole zones continue to be evaluated. PetroCorp has working interest varying from 2.4% to 32.5% in the surrounding 12,800 leased acres. XI-2 Production and Sales The following table presents certain information with respect to oil and gas production attributable to the Company's properties, average sales price received and average production costs during the three years ended December 31, 2000, 1999, and 1998. The average oil sales price and average gas sales price have been reduced, respectively, by $1,035,000 ($2.56 per Bbl) and $62,000 ($0.01 per Mcf) for hedging losses during 2000. See Note 9 to the Consolidated Financial Statements of the Company and "Supplemental Information to the Consolidated Financial Statements" in the Notes thereto included elsewhere in this report for additional financial information regarding the Company's foreign and domestic operations.

This gas is typically sold under short-term contracts ranging in length from one month to one year. In Canada during 2000, nearly one-half of the Company's gas was dedicated under long-term contracts to Pan-Alberta Gas Ltd. (Pan- Alberta), a major Canadian gas aggregator and marketer. Under these contracts, approximately 75% of the gas was resold into the United States, predominantly to markets in the upper Midwest region. PetroCorp received a price, per Mcf, from Pan-Alberta equal to Pan-Alberta's resale price less certain costs. Most of the Company's remaining Canadian gas was sold to Engage Energy at spot prices on either a daily or a monthly basis. PetroCorp's domestic crude oil and condensate production is sold to a variety of purchasers typically on a monthly contract basis at posted field prices or NYMEX prices, as determined by major buyers. In particular XI-3 areas, where production volumes are significant or the location is desirable for a particular purchaser, or both, the Company has successfully negotiated bonuses over the purchaser's general field postings for its production. During the year ended December 31, 2000, Engage Energy and Pan-Alberta accounted for 27% and 19% of the Company's total sales, respectively. The Company does not believe the loss of any purchaser would have a material adverse effect on its financial position since the Company believes alternative sales arrangements could be made on relatively comparable terms. In general, prices of oil and gas are dependent on numerous factors beyond the control of the Company, such as competition, international events and circumstances (including actions taken by the Organization of Petroleum Exporting Countries (OPEC)), and certain economic, political and regulatory developments. Since demand for natural gas is generally highest during winter months, prices received for the Company's natural gas are subject to seasonal variations. Hedging Activities Prior to 1997, the Company utilized hedging transactions to manage its exposure to price fluctuations in crude oil and natural gas. The Company has reviewed this strategy and has begun hedging activities again, effective April 2000. No contracts were outstanding as of December 31, 2000. See "Management's Discussion and Analysis of Financial Condition and Results of Operations" for the impact of hedging transactions on financial results. Competition The oil and gas industry is highly competitive. The Company competes in acquisitions and in the exploration, development, production and marketing of oil and gas with major oil companies, larger independent oil and gas concerns and individual producers and operators. Many of these competitors have substantially greater financial and other resources than the Company. Regulation United States General. The Company's business is affected by numerous governmental laws and regulations, including energy, environmental, conservation and tax laws. For example, state and federal agencies have issued rules and regulations that require permits for the drilling of wells, regulate the spacing of wells, prevent the waste of reserves through proration, and regulate oilfield and pipeline environmental and safety matters. Changes in any of these laws could have a material adverse effect on the Company's business, and the Company cannot predict the overall effects of such laws and regulations on its future operations. Although these regulations have an impact on the Company and others in the oil and gas industry, the Company does not believe that it is affected in a significantly different manner by these regulations than are its competitors in the oil and gas industry. The following discussion contains summaries of certain laws and regulations and is qualified in its entirety by the foregoing. Regulation of Transportation and Sale of Natural Gas and Oil. Various aspects of the Company's oil and gas operations are regulated by agencies of the federal government. The transportation of natural gas in interstate commerce is generally regulated by the Federal Energy Regulatory Commission (FERC) pursuant to the Natural Gas Act of 1938 (the NGA) and the Natural Gas Policy Act of 1978 (NGPA). The intrastate transportation and gathering of natural gas (and operational and safety matters related thereto) may be subject to regulation by state and local governments. In the past, the federal government regulated the prices at which the Company's produced oil and gas could be sold. Currently, "first sales" of natural gas by producers and marketers, and all sales of crude oil, condensate XI-4 and natural gas liquids, can be made at uncontrolled market prices, but Congress could reenact price controls at any time. Within the past decade, the FERC has issued numerous orders and policy statements designed to create a more competitive environment in the national natural gas marketplace, including orders promoting "open-access" transportation on natural gas pipelines subject to the FERC's NGA and NGPA jurisdiction. The FERC's "Order 636" was issued in April 1992 and was designed to restructure the interstate natural gas transportation and marketing system and to promote competition within all phases of the natural gas industry. Among other things, Order 636 required interstate pipelines to separate the transportation of gas from the sale of gas, to change the manner in which pipeline rates were designed and to implement other changes intended to promote the growth of market centers. Subsequent FERC initiatives have attempted to standardize interstate pipeline business practices and to allow pipelines to implement market-based, negotiated and incentive rates. The restructured services implemented by Order 636 and successor orders have now been in effect for a number of winter heating seasons and have significantly affected the manner in which natural gas (both domestic and foreign) is transported and sold to consumers. Order 636 has generally been upheld in judicial appeals to date. However, FERC routinely evaluates whether its approach to regulation of the natural gas industry should be changed and whether further refinements or changes to existing policies should be made in view of developments in the natural gas industry since Order 636 was originally issued. Although FERC has indicated that it remains committed to Order 636's "fundamental goal" of "improving the competitive structure of the natural gas industry in order to maximize the benefits of wellhead decontrol," the future regulatory goals and priorities of FERC may change, and it is not possible to predict the effect, if any, of future restructuring orders or policies on the Company's operations. FERC's policies may also be impacted by the ongoing restructuring of the electric power industry pursuant to FERC Order No. 888. While Order 636 and related orders do not directly regulate either the production or sale of gas that may be produced from the Company's properties, the increased competition and changes in business practices within the natural gas industry resulting from such orders have affected the terms and conditions under which the Company markets and transports its available gas supplies. To date, the FERC's pro-competition policies have not materially affected the Company's business or operations. On a prospective basis, however, such orders may substantially increase the burden on producers and transporters to accurately nominate and deliver on a daily basis specified volumes of natural gas, or to bear penalties or increased costs in the event scheduled deliveries are not made. Environmental Regulation. Various federal, state and local laws and regulations governing the discharge of materials into the environment, or otherwise relating to the protection of the environment, may affect the Company's operations and costs. In particular, the Company's exploration, exploitation and production operations, its activities in connection with storage and transportation of crude oil and other liquid hydrocarbons and its use of facilities for treating, processing or otherwise handling hydrocarbons and wastes therefrom are subject to stringent environmental regulation. Although compliance with these regulations increases the cost of Company operations, such compliance has not in the past had a material effect on the Company's capital expenditures, earnings or competitive position. Environmental regulations have historically been subject to frequent change by regulatory authorities. The trend toward stricter standards in environmental legislation and regulation is likely to continue. For instance, legislation has been proposed in Congress from time to time that would reclassify certain oil and gas exploration and production wastes as "hazardous wastes," which would make the reclassified wastes subject to much more stringent handling, disposal and cleanup requirements. If such legislation were to be enacted, it could have a significant impact on the operating costs of the Company, as well as the oil and gas industry in general. Also at the federal level, the U.S. Oil Pollution Act requires owners and operators of facilities that could be the source of an oil spill into "waters of the United States" (a term defined to include rivers, creeks, wetlands and coastal waters) to demonstrate that they have at least $35 million in financial resources to pay for the costs of cleaning up an oil spill and compensating any parties damaged by an oil spill. Such financial assurances may be increased to as much as $150 million if a formal assessment indicates XI-5 such an increase is warranted. These financial responsibility requirements could have a significant adverse impact on small oil and gas companies like PetroCorp. State initiatives to further regulate the disposal of oil and gas wastes are also pending in certain states, and these various initiatives could have a similar impact on the Company. The Company is unable to predict the ongoing cost to it of complying with these laws and regulations or the future impact of such regulations on its operation. Management believes that the Company is in substantial compliance with current applicable environmental laws and regulations and that continued compliance with existing requirements will not have a material adverse impact on the Company. A catastrophic discharge of hydrocarbons into the environment could, to the extent such event is not insured, subject the Company to substantial expense. Canada In Canada, the petroleum industry operates under federal, provincial and municipal legislation and regulations governing taxes, land tenure, royalties, production rates, environmental protection, exports and other matters. Prices of oil and natural gas in Canada have been deregulated and are determined by market conditions and negotiations between buyers and sellers, although oil production volumes are regulated. Various matters relating to the transportation and distribution of natural gas are the subject of hearings before various regulatory tribunals. In addition, although the price of natural gas exported from Canada is subject to negotiation between buyers and sellers, the National Energy Board, which regulates exports of natural gas, requires that natural gas export contracts meet certain criteria as a condition of approving such contracts. These criteria, including price considerations, are designed to demonstrate that the export is in the Canadian public interest. Several provincial governments have introduced a number of programs to encourage and assist the oil and natural gas industry, including incentive payments, royalty holidays and royalty tax credits. Canadian governmental regulations may have a material effect on the economic parameters for engaging in oil and gas activities in Canada and may have a material effect on the advisability of investments in Canadian oil and gas drilling activities. Employees At December 31, 2000, PetroCorp had 2 full-time employees. (See "Restructuring" included in Item 7--Management's Discussion and Analysis of Financial Condition and Result of Operations.) Item 2. Properties. Principal Properties The Company's proved oil and gas properties are relatively concentrated. Approximately 76% of the PV-10 from the Company's proved reserves at December 31, 2000 was attributable to four principal areas. The following table presents data regarding the estimated quantities of proved oil and gas reserves and the PV-10 attributable to the Company's principal properties as of December 31, 2000, all of which are taken from reports prepared by Huddleston & Co., Inc. in accordance with the rules and regulations of the Securities and Exchange Commission (SEC).

PetroCorp's largest single producing area is the Hanlan-Robb natural gas production complex located in the foothills region of western Alberta, Canada, which accounted for approximately 42% of the Company's 2000 net daily gas production. The Company owns an interest in eleven producing fields in this area, covering 46,000 developed acres, with current combined production of 240 MMcf/D. PetroCorp has additional interests in 80,000 undeveloped acres in this area. The key field is the Hanlan Swan Hills Gas Unit #1, with a current gross production of 134 MMcf/D. PetroCorp's ownership is part of a joint venture managed by the Company with institutional investors that collectively own 21.7% of the field. PetroCorp's working interest in this field is 35% of the joint venture, or 7.6%. Petro-Canada (not an affiliate of PetroCorp) is the largest interest owner in the area and operates the Hanlan- Robb area fields and the related gathering system and processing plant. Other PetroCorp fields in this area include Shaw/Basing, Minehead, Columbia, Red Cap, Lambert, Banshee and Medicine Lodge. Oklahoma City Area. Includes the Southwest Oklahoma City Field located within the metropolitan Oklahoma City area in Oklahoma and the Edmond Prospect located just north of Oklahoma City. In the Southwest Oklahoma City Field area, PetroCorp operates 61 wells and has a working interest in two additional wells. The Company also owns a 4% working interest in the adjacent Will Rogers Unit, operated by Marathon. The key property is the PetroCorp operated SW Oklahoma City Unit, a field-wide waterflood unit targeting the Prue formation at 6,500 feet. Current unit production is approximately 400 BOPD and 2,200 Mcf/D. The Company owns an 86.4% working interest in the unit. South Louisiana Area. Includes ownership in the East Riceville Field in Vermillion Parish and the Scott Field in Lafayette Parish. East Riceville is a two-well gas field producing 16 MMcf/D from a Miogyp reservoir at approximately 17,000 feet. PetroCorp owns a 13.8% working interest in this field, which is operated by Murphy Exploration and Production Company. McLeod Field. As part of an acquisition in late 1996, the Company acquired one shut-in oil well in this field in west central Alberta, Canada. Since then, PetroCorp has drilled seven successful wells and acquired an interest in two producing wells. A gas conservation project is expected to be completed in early 2001 to capture flared solution gas from the oil wells. The Company's working interests vary from 12% to 100% in 9.8 sections (approximately 6,240 acres). Other Properties. Other significant U.S. properties include the Glick Field located in south-central Kansas, the Hunter Misener Unit located in Alfalfa County, Oklahoma, the Maynor Creek Field in Wayne County, Mississippi, the Harris Field in Live Oak County, Texas, and the Paradox Basin area of southwest Colorado. Other significant Canadian properties include the Trochu Prospect in south-central Alberta and the Worsley Triassic A Pool located on the north flank of the Peace River Arch in Alberta. Title to Properties United States. Except for the Company-owned mineral fee, royalty and overriding royalty interests shown in the "Acreage and Wells" table below, substantially all of the Company's United States property interests are held pursuant to leases from third parties. The Company believes that it has satisfactory title to its properties in accordance with standards generally accepted in the oil and gas industry. In numerous instances, the Company has acquired legal title to producing properties and has carved out of the properties so acquired net profits royalty interests in favor of institutional investors who supplied a substantial portion of the funds for the acquisition of such properties. The producing property reserves of the Company are stated after giving effect to the reduction in cash flow attributable to such net profits royalty interests. In addition, the Company's properties are subject to customary royalty interests, liens for current taxes and other burdens that the Company believes do not materially interfere with the use of or affect the value of such properties. Canada. Canadian property interests are held primarily under leases from the Crown. A small percentage are from freehold owners. Prior to drilling on a non- Crown lease or acquiring a non-Crown producing lease, the Company generally obtains a title opinion covering the "historical" (freehold) title. The Company generally XI-7 relies on a title certificate under Canada's Torrens title registration system to verify "current" (leasehold) ownership. Except for these differences, title matters in Canada are similar to those in the United States. Oil and Gas Reserves All information herein regarding estimates of the Company's proved reserves, related future net revenues and PV-10 is taken from reports prepared by Huddleston & Co., Inc. (the Independent Engineers) in accordance with the rules and regulations of the SEC. The Independent Engineers' estimates were based upon a review of production histories and other geologic, economic, ownership and engineering data provided by the Company. The following table sets forth summary information with respect to the estimates made by the Independent Engineers of the Company's proved oil and gas reserves as of December 31, 2000. The PV-10 values shown in the table are not intended to represent the current market value of the estimated oil and gas reserves owned by the Company. The average prices used in determining future cash inflows for natural gas and oil as of December 31, 2000, were $9.19 per Mcf and $27.16 per barrel, respectively. These prices were based on the adjusted cash spot price for natural gas and oil at December 31, 2000. These prices are significantly higher than the average natural gas and oil price received by PetroCorp during December 2000, and the prices PetroCorp expects to receive during 2001 and ensuing years.

Reserve engineering is a subjective process of estimating underground accumulations of crude oil and natural gas that cannot be measured in an exact manner, and the accuracy of any reserve estimate is a function of the quality of available data and of engineering and geological interpretation and judgment. Estimates of proved undeveloped reserves are inherently less certain than estimates of proved developed reserves. The quantities of oil and gas that are ultimately recovered, production and operating costs, the amount and timing of future development expenditures, geologic success and future oil and gas sales prices may all differ from those assumed in these estimates. In addition, the Company's reserves may be subject to downward or upward revision based upon production history, purchases or sales of properties, results of future development, prevailing oil and gas prices and other factors. Therefore, the present value shown above should not be construed as the current market value of the estimated oil and gas reserves attributable to the Company's properties. In accordance with SEC guidelines, the Independent Engineers' estimates of future net revenues from the Company's proved reserves and the present value thereof are made using oil and gas sales prices in effect as of the dates of such estimates and are held constant throughout the life of the properties except where such guidelines permit alternate treatment, including, in the case of gas contracts, the use of fixed and determinable XI-8 contractual price escalations. See "Marketing" under Item 1 of this report, "Management's Discussion and Analysis of Financial Condition and Results of Operations" under Item 7 of this report and "Supplemental Information to Consolidated Financial Statements" in the Notes to the Consolidated Financial Statements of the Company. Estimates of the Company's proved oil and gas reserves were not filed with or included in reports to any other federal authority or agency other than the SEC during the fiscal year ended December 31, 2000. Acreage and Wells The following table sets forth certain information with respect to the Company's developed and undeveloped leased acreage as of December 31, 2000.

As of December 31, 2000, the Company had working interests in 233 gross (75 net) producing oil wells and 197 gross (35 net) producing gas wells. Of these wells, 20 gross (18 net) oil wells and 56 gross (11 net) gas wells were in Canada, and the remainder of the oil and gas wells were in the United States. XI-9 Drilling Activities All of PetroCorp's drilling activities are conducted through arrangements with independent contractors, and it owns no drilling equipment. Certain information with regard to the Company's drilling activities completed during the years ended December 31, 2000, 1999 and 1998 is set forth below: Year Ended December 31, ---------------------------------------------- 2000 1999 1998 -------------- -------------- -------------- Net Net Net Working Working Working Type of Well Gross Interest Gross Interest Gross Interest ------------ ----- -------- ----- -------- ----- -------- United States Development: Oil........................... 4 .2 4 .2 -- -- Gas........................... 5 .3 1 .0(1) 9 1.3 Nonproductive................. 1 .2 1 .2 -- -- --- --- --- --- --- --- Total....................... 10 .7 6 .4 9 1.3 --- --- --- --- --- --- Exploratory: Oil........................... -- -- -- -- -- -- Gas........................... -- -- -- -- 2 .3 Nonproductive................. 1 .0(1) 1 .2 8 2.6 --- --- --- --- --- --- Total....................... 1 .0 1 .2 10 2.9 --- --- --- --- --- --- Canada Development: Oil........................... 1 1 1 1 -- -- Gas........................... 6 1.1 2 .2 2 .1 Nonproductive................. -- -- 2 .0(1) -- -- --- --- --- --- --- --- Total....................... 7 2.1 5 1.2 2 .1 --- --- --- --- --- --- Exploratory: Oil........................... -- -- -- -- -- -- Gas........................... 3 .4 4 .2 2 1.1 Nonproductive................. -- -- 3 .1 2 1.2 --- --- --- --- --- --- Total....................... 3 .4 7 .3 4 2.3 --- --- --- --- --- --- Total........................... 21 3.2 19 2.1 25 6.6 === === === === === === - -------- (1) The Company has a net working interest less than 0.05% in these wells. At December 31, 2000, the Company was participating in the drilling of 3 gross (.3 net) wells. Of these, 1 gross (.1 net) was in the United States and 2 gross (.2 net) were in Canada. Hanlan-Robb Natural Gas Processing Plant and Gas Gathering Systems PetroCorp owns interests in a centrally located gas processing plant and in a gas gathering system that connects all of the Company's currently producing Hanlan-Robb fields to the Hanlan-Robb plant. Commissioned in 1983, the estimated replacement value is approximately $340 ($C500) million. The original design capacity of 300 MMcf/D has been expanded to 380 MMcf/D and two new major pipeline systems began delivering third-party gas to the plant for processing in September 1998. This third-party gas, for which processing fees are received, plus gas from additional drilling in the area, has increased plant throughput from 220 MMcf/D to approximately 340 MMcf/D at year-end 2000. PetroCorp owns a 24.5% working interest in the plant and varying working interests in the gathering systems, dehydration and compression facilities that deliver gas to the plant. XI-10 Previously a wholly-owned subsidiary of the Company, Fidelity Gas Systems, Inc. ("FGS"), owned and operated the Anasazi Gas Gathering System, which gathers gas produced from the Company-operated lease in the Paradox Basin area of southwest Colorado. In December 1997, FGS was merged into the Company. The working interest owners have entered into contracts with the Company pursuant to which the Company purchases all of the gas produced from the area. This gas is then resold by the Company to a purchaser at a redelivery point on the national transmission pipeline system. Proceeds payable by the Company are based upon the Company's resale price less a contractually agreed-upon fee. Amounts received by the Company are distributed to all working interest and royalty owners in the producing area in accordance with their ownership interests. Because it is a gas gathering system, the Anasazi Gas Gathering System has been deemed nonjurisdictional with respect to existing FERC rules and regulations. Other Facilities In 2000, the Company found a replacement lessee for approximately 31,600 square feet in Houston, Texas where its primary office was previously located. The Company leases, and subleases to others, approximately 8,200 square feet in Oklahoma City, Oklahoma and approximately 4,000 square feet in Calgary, Alberta where divisional offices were previously located. The obligation under these leases will end in 2001 for the Oklahoma City lease and 2002 for the Calgary lease. Additionally, the Company owns an 18,400 square-foot building and surface pads covering approximately 42 acres related to its Southwest Oklahoma City Field operations. FORWARD-LOOKING STATEMENTS AND RISK FACTORS Current and prospective stockholders should carefully consider the following risk factors in evaluating an investment in PetroCorp. The information discussed herein includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the "Securities Act"), and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). All statements other than statements of historical facts included herein regarding planned capital expenditures, increases in oil and gas production, the number of anticipated wells to be drilled after the date hereof, the Company's financial position, business strategy and other plans and objectives for future operations, are forward-looking statements. Although the Company believes that the expectations reflected in such forward-looking statements are reasonable, they do involve certain assumptions, risks and uncertainties, and the Company can give no assurance that such expectations will prove to have been correct. The Company's actual results could differ materially from those anticipated in these forward-looking statements as a result of certain factors, including those set forth in the following risk factors. All subsequent written and oral forward-looking statements attributable to the Company or persons acting on its behalf are expressly qualified in their entirety by such factors. Volatile Nature of Oil and Gas Markets; Fluctuations in Prices The Company's future financial condition and results of operations are highly dependent on the demand and prices received for oil and gas production and on the costs of acquiring, developing and producing reserves. Oil and gas prices have historically been volatile and are expected by the Company to continue to be volatile in the future. Prices for oil and gas are subject to wide fluctuation in response to relatively minor changes in the supply of and demand for oil and gas, market uncertainty and a variety of additional factors that are beyond the Company's control. These factors include political conditions in the Middle East and elsewhere, domestic and foreign supply of oil and gas, the level of consumer demand, weather conditions, domestic and foreign government regulations and taxes, the price and availability of alternative fuels and overall economic conditions. A decline in oil or gas prices may adversely affect the Company's cash flow, liquidity and profitability. Lower oil or gas prices also may reduce the amount of the Company's oil and gas that can be produced economically. XI-11 Dependence on Acquiring and Finding Additional Reserves The Company's prospects for future growth and profitability will depend predominantly on its ability to replace present reserves through acquisitions and exploratory drilling, as well as on its ability to successfully develop additional reserves. There can be no assurance that the Company's acquisition and exploration activities or planned development projects will result in significant additional reserves or that the Company will have continuing success at drilling economically productive wells. Substantial Capital Requirements The Company has made substantial capital expenditures in connection with the acquisition, exploration and development of oil and gas properties. Future cash flows and the availability of credit are subject to a number of variables, such as the level of production from existing wells, prices of oil and gas and the Company's success in locating and producing new reserves. If revenues were to decrease as a result of lower oil and gas prices, decreased production or otherwise, and the Company had no available credit, the Company could be limited in its ability to replace its reserves or to maintain production at current levels, resulting in a decrease in production and revenue over time. If the Company's cash flow from operations and available credit are not sufficient to satisfy its capital expenditure requirements, there can be no assurance that additional debt or equity financing will be available to meet these requirements. Reliance on Estimates of Reserves and Future Net Cash Flows There are numerous uncertainties inherent in estimating quantities of proved oil and gas reserves, including many factors beyond the Company's control. Petroleum engineering is a subjective process of estimating underground accumulations of oil and gas that cannot be measured in an exact manner. Estimates of economically recoverable oil and gas reserves and of future net cash flow necessarily depend upon a number of variable factors and assumptions, such as historical production from the area compared with production from other producing areas, the assumed effects of regulation by governmental agencies, assumptions concerning future oil and gas prices, future operating costs, severance and excise taxes, development costs and workover and remedial costs, all of which may in fact vary considerably from actual results. For these reasons, estimates of the economically recoverable quantities of oil and gas attributable to any particular group of properties, classifications of such reserves based on risk of recovery and estimates of the future net cash flows expected therefrom prepared by different engineers or by the same engineers at different times may vary significantly. Actual production, revenues and expenditures with respect to the Company's reserves likely will vary from estimates, and such variances may be material. In addition, the Company's reserves and future cash flows may be subject to revisions based upon production history, results of future development, oil and gas prices, performance of counterparties under agreements to which the Company is a party, operating and development costs and other factors. The PV-10 values referred to herein should not be construed as the current market value of the estimated oil and gas reserves attributable to the Company's properties. In accordance with applicable requirements of the SEC, the PV-10 values are generally based on prices and costs as of the date of the estimate, whereas actual future prices and costs may be materially higher or lower. Actual future net cash flows also will be affected by factors such as the amount and timing of actual production, supply and demand for oil and gas, curtailments or increases in consumption by natural gas purchasers and changes in governmental regulations or taxation. The timing of actual future net cash flows from proved reserves, and thus their actual present value, will be affected by the timing of both the production and the incurrence of expenses in connection with development and production of oil and gas properties. In addition, the 10% discount factor (which is required by the SEC to be used to calculate PV-10 for reporting purposes), is not necessarily the most appropriate discount factor based on interest rates in effect from time to time and risks associated with the Company and its properties or the oil and gas industry in general. XI-12 Exploration Risks Exploratory drilling activities are subject to many risks, including the risk that no commercially productive reservoirs will be encountered, and there can be no assurance that new wells drilled by the Company will be productive or that the Company will recover all or any portion of its investment. Drilling for oil and gas may involve unprofitable efforts, not only from non-productive wells, but from wells that are productive but do not produce sufficient net revenues to return a profit after drilling, operating and other costs. The cost of drilling, completing and operating wells is often uncertain. The Company's drilling operations may be curtailed, delayed or canceled as a result of numerous factors, many of which are beyond the Company's control, including title problems, weather conditions, compliance with governmental requirements and shortages or delays in the delivery of equipment and services. Marketing Risks The Company's ability to market its oil and gas production at commercially acceptable prices is dependent on, among other factors, the availability and capacity of gathering systems and pipelines, federal and state regulation of production and transportation, general economic conditions, and changes in supply and in demand. Acquisition Risks Acquisitions of oil and gas businesses and properties and volumetric production payments have been an important element of the Company's success, and the Company will continue to seek acquisitions in the future. Even though the Company performs a review (including a limited review of title and other records) of the major properties it seeks to acquire that it believes is consistent with industry practices, such reviews are inherently incomplete and it is generally not feasible for the Company to review in-depth every property and all records. Even an in-depth review may not reveal existing or potential problems or permit the Company to become familiar enough with the properties to assess fully their deficiencies and capabilities, and the Company often assumes environmental and other liabilities in connection with acquired businesses and properties. Operating Risks The Company's operations are subject to numerous risks inherent in the oil and gas industry, including the risks of fire, explosions, blow-outs, pipe failure, abnormally pressured formations and environmental accidents such as oil spills, natural gas leaks, ruptures or discharges of toxic gases, the occurrence of any of which could result in substantial losses to the Company due to injury or loss of life, severe damage to or destruction of property, natural resources and equipment, pollution or other environmental damage, clean-up responsibilities, regulatory investigation and penalties and suspension of operations. The Company's operations may be materially curtailed, delayed or canceled as a result of numerous factors, including the presence of unanticipated pressure or irregularities in formations, accidents, title problems, weather conditions, compliance with governmental requirements and shortages or delays in the delivery of equipment. In accordance with customary industry practice, the Company maintains insurance against some, but not all, of the risks described above. There can be no assurance that the levels of insurance maintained by the Company will be adequate to cover any losses or liabilities. Competitive Industry The oil and gas industry is highly competitive. The Company competes for corporate and property acquisitions and the exploration, development, production, transportation and marketing of oil and gas, as well as contracting for equipment and securing personnel, with major oil and gas companies, other independent oil and gas concerns and individual producers and operators. Many of these competitors have financial and other resources which substantially exceed those available to the Company. XI-13 Risks That Might Arise from the Management Agreement Potential operational inefficiencies may occur during a transition period. Although a change is not currently anticipated, the Management Agreement with Kaiser-Francis provides for termination by either party after a six-month notice. In that unlikely event, some operational inefficiencies may occur as replacement personnel become familiar with the Company's properties and operations. Government Regulation The Company's business is subject to certain federal, state and local laws and regulations relating to the drilling for and production, transportation and marketing of oil and gas, as well as environmental and safety matters. Such laws and regulations have generally become more stringent in recent years, often imposing greater liability on an increasing number of parties. Because the requirements imposed by such laws and regulations are frequently changed, the Company is unable to predict the effect or cost of compliance with such requirements or their effects on oil and gas use or prices. In addition, legislative proposals are frequently introduced in Congress and state legislatures which, if enacted, might significantly affect the oil and gas industry. In view of the many uncertainties which exist with respect to any legislative proposals, the effect on the Company of any legislation which might be enacted cannot be predicted. Item 3. Legal Proceedings. The Company is a party to various lawsuits and governmental proceedings, all arising in the ordinary course of business. Although the outcome of these lawsuits cannot be predicted with certainty, the Company does not expect such matters to have a material adverse effect, either singly or in the aggregate, on the financial position of the Company. Item 4. Submission of Matters to a Vote of Security Holders. None. XI-14 PART II Item 5. Market for Registrant's Common Equity and Related Stockholder Matters. The Company's Common Stock is currently listed on the American Stock Exchange (the "AMEX") and trades under the symbol PEX. The Company's Common Stock has been listed with the AMEX since September 17, 1998. Prior to that time, the Company's Common Stock had been listed on The Nasdaq Stock Market since October 28, 1993. The following table presents the high and low closing prices for the Company's Common Stock for each quarter during 1999 and 2000, and for a portion of the Company's current quarter, as reported by the AMEX. 1999 2000 2001 ------------------------------- ------------------------------- ------------------------- First Quarter First Second Third Fourth First Second Third Fourth (through Quarter Quarter Quarter Quarter Quarter Quarter Quarter Quarter February 28) ------- ------- ------- ------- ------- ------- ------- ------- ------------- High.................... $5.88 $6.13 $7.50 $6.88 $6.75 $7.25 $9.88 $10.19 $10.63 Low..................... 5.19 4.38 5.50 5.75 5.25 5.50 7.00 8.63 9.69 As of February 28, 2001, the closing price for the Company's Common Stock was $9.75 per share. As of February 28, 2001, there were approximately 500 holders of record of the Common Stock. The Company has not declared or paid any cash dividends on its Common Stock to date. The Board of Directors of the Company does not intend to declare cash dividends on its Common Stock in the foreseeable future. The Company intends instead to retain its earnings to support the growth of the Company's business. Any future cash dividends would depend on future earnings, capital requirements, the Company's financial condition and other factors deemed relevant by the Company's Board of Directors. The terms of the Company's credit facility prohibits the declaration or payment of any dividends. XI-15 Item 6. Selected Financial Data. The following table summarizes consolidated financial data of the Company and should be read in conjunction with the "Management's Discussion and Analysis of Financial Condition and Results of Operations" and the Consolidated Financial Statements of the Company, including the Notes thereto, included elsewhere in this report.

XI-16 Item 7. 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: For the Year Ended December 31, ----------------------- 2000 1999 1998 ------- ------- ------- Production: United States: Oil (Mbbls)..................................... 294 324 422 Gas (MMcf)...................................... 3,850 4,421 4,932 Gas equivalents (MMcfe)......................... 5,614 6,365 7,464 Canada: Oil (Mbbls)..................................... 110 138 143 Gas (MMcf)...................................... 4,519 4,660 4,579 Gas equivalents (MMcfe)......................... 5,179 5,488 5,437 Total: Oil (Mbbls)..................................... 404 462 565 Gas (MMcf)...................................... 8,369 9,081 9,511 Gas equivalents (MMcfe)......................... 10,793 11,853 12,901 Average sales prices: United States: Oil (per Bbl)................................... $ 26.38 $ 17.33 $ 12.55 Gas (per Mcf)................................... 4.08 2.24 2.15 Canada: Oil (per Bbl)................................... 25.49 16.48 11.59 Gas (per Mcf)................................... 3.54 1.58 1.32 Weighted average: Oil (per Bbl)................................... 26.14 17.08 12.31 Gas (per Mcf)................................... 3.79 1.90 1.75 Selected data per Mcfe: Average sales price.............................. $ 3.92 $ 2.13 $ 1.83 Production costs................................. 0.74 0.57 0.57 General and administrative expenses.............. 0.14 0.36 0.35 Oil and gas depreciation, depletion and amortization.................................... 0.74 0.69 1.16 Restructuring As part of a restructuring plan, on August 3, 1999, PetroCorp's Board of Directors entered into a Management Agreement with its largest shareholder, Kaiser-Francis, under which Kaiser-Francis provides management, technical, and administrative support services for all PetroCorp operations in the United States and Canada. Under the terms of the Management Agreement, as amended, Kaiser-Francis is compensated through a service fee equal to administrative and overhead fees charged under applicable operating agreements plus fixed XI-17 fees of no more than $50 per well for non-operated properties. Fees for 2000 and 1999, respectively, were $1,419,000 and $218,000. The Company recorded restructuring costs of $3,643,000 during 1999. Included in the costs are employee termination costs of $2,371,000, $807,000 in nonrefundable office lease discontinuance, $363,000 in investment banking and legal costs, and $102,000 in other related costs. As of December 31, 1999, $2,161,000 of the restructuring costs are included in accrued liabilities. As a result of the restructuring, fifty-two employees were terminated in 1999 with one employee terminated in 2000. Several employees elected to defer receipt of their termination benefits until 2000. The Houston, Oklahoma City and Calgary offices were closed but the Company was still liable under the lease agreements. In the second quarter of 2000, the Company was able to find a replacement lessee for some of the idle office space earlier than anticipated. The following table shows the change in accrued restructuring costs during 2000: Balance at Expenditures Balance at December 31, charged Changes December 31, 1999 against accrual in estimates 2000 ------------ --------------- ------------ ------------ Employee termination costs.................. $1,341,000 $1,341,000 $ -- $ -- Office lease discontinuance and other related costs.... 820,000 305,000 (445,000) 70,000 ---------- ---------- --------- ------- $2,161,000 $1,646,000 $(445,000) $70,000 ========== ========== ========= ======= Results of Operations 2000 Compared to 1999 Overview. The Company recorded net income of $12,818,000 or $1.47 per share in 2000, compared to a loss of $206,000, or $0.02 per share, for the corresponding period of 1999. This improvement results from higher oil and gas prices and lower general and administrative, restructuring costs and depreciation, depletion, and amortization expenses. Revenues. Total revenues increased 64% to $44.6 million in 2000 compared to $27.1 million in 1999. Oil production decreased 13% to 404 MBbls from 462 MBbls. Natural gas production decreased 8% to 8,369 MMcf from 9,081 MMcf, resulting in overall production decreasing 9% to 10,793 MMcfe from 11,853 MMcfe. Production decreases are due to normal production declines. The Company's average U.S. natural gas price increased 82% to $4.08 per Mcf in 2000 from $2.24 per Mcf in 1999, while the average Canadian natural gas price increased 124% to $3.54 from $1.58. The Company's composite average oil price increased 53% to $26.14 per barrel in 2000 from $17.08 per barrel in 1999. Primarily as a result of price increases, oil and gas revenues increased 68% to $42.3 million in 2000 from $25.2 million in 1999. Plant processing revenues increased 8% to $1.9 million from $1.8 million primarily as a result of new third party processing in the Canadian Hanlan-Robb gas processing plant. Production Costs. Production costs increased 19% to $8.0 million in 2000 compared to $6.7 million in 1999 as a result of workover operations for repairs and production enhancements and production tax increases related to higher commodity prices. Production costs per Mcfe were $0.74 for 2000 and $0.57 for 1999. Approximately $0.18 per Mcfe of increased costs are due to workover operations and increased production taxes. Depreciation, Depletion & Amortization (DD&A). Total DD&A decreased 4% to $9.5 million in 2000 from $9.9 million in 1999. The increase in the oil and gas DD&A rate per Mcfe to $0.74 in 2000 from $0.69 in 1999 reflects the impact of previously unevaluated properties evaluated in 2000 and moved into the full cost pool. General and Administrative Expenses. General and administrative expenses decreased 65% to $1.5 million in 2000 from $4.3 million in 1999 as a result of the Company's restructuring efforts and the Management Agreement with Kaiser- Francis. XI-18 Investment Income. Investment income decreased less than 1% to $584,000 in 2000 from $585,000 in 1999. Interest Expense. Interest expense decreased 13% to $3.4 million in 2000 from $3.9 million in 1999, reflecting the impact of reduced debt levels, partially offset by an increase in interest rates. Income Taxes. The Company recorded a $10.1 million income tax expense on pre-tax income of $23.2 million with an effective tax rate of 44% in 2000 compared to an income tax benefit of $954,000 on a pre-tax loss of $1.2 million with an effective tax rate of 82% in 1999. During 2000, the Company recorded an income tax provision for its Canadian operations with an effective tax rate of 47% and tax provision for its U.S. operations with an effective tax rate of 39%, resulting in an overall effective tax rate of 44%. Effective tax rates in excess of statutory rates are primarily due to adjustments of approximately $1.2 million resulting from audits by Canadian tax authorities. 1999 Compared to 1998 Overview. Net loss decreased 99% to a loss of $.2 million, or $0.02 per share, compared to a loss of $24.4 million, or $2.82 per share, for the corresponding period. Net income in 1998 was significantly impacted by a $33.6 million oil and gas property valuation adjustment while 1999 net income was impacted by $3,643,000 of restructuring costs. Revenues. Total revenues increased 7% to $27.1 million in 1999 compared to $25.2 million in 1998. Oil production decreased 18% to 462 MBbls from 565 MBbls. Natural gas production decreased 5% to 9,081 MMcf from 9,511 MMcf, resulting in overall production decreasing 8% to 11,853 MMcfe from 12,901 MMcfe. The Company's average U.S. natural gas price increased 4% to $2.24 per Mcf in 1999 from $2.15 per Mcf in 1998, while the average Canadian natural gas price increased 20% to $1.58 from $1.32. The Company's composite average oil price increased 39% to $17.08 per barrel in 1999 from $12.31 per barrel in 1998. Primarily as a result of price increases, oil and gas revenues increased 7% to $25.2 million in 1999 from $23.6 million in 1998. Plant processing revenues increased 15% to $1.8 million from $1.6 million primarily as a result of new third party processing in the Canadian Hanlan-Robb gas processing plant. Production Costs. Production costs decreased 8% to $6.7 million in 1999 compared to $7.3 million in 1998 primarily as a result of the 8% decrease in production volumes. Production costs per Mcfe were $0.57 for both 1999 and 1998. Depreciation, Depletion & Amortization (DD&A). Total DD&A decreased 40% to $9.9 million in 1999 from $16.6 million in 1998. The decrease in the oil and gas DD&A rate per Mcfe to $0.69 in 1999 from $1.16 in 1998 reflects the impact of the year-end 1999 increase in proved reserves and the impact of the 1998 oil and gas property valuation adjustment. General and Administrative Expenses. General and administrative expenses decreased 4% to $4.3 million in 1999 from $4.5 million in 1998. The overall decrease is primarily due to cost reduction efforts, including reductions in personnel. This decrease was partially offset by $805,000 of incentives paid to now-terminated employees to induce them to stay through the close down of existing offices. Investment Income. Investment and other income decreased 49% to $585,000 in 1999 from $1.2 million in 1998, primarily as a result of gas contract settlements received in 1998. Interest Expense. Interest expense increased 7% to $3.9 million in 1999 from $3.6 million in 1998, reflecting the impact of increased debt associated with a producing property acquisition completed in June 1998. Income Taxes. The Company recorded a $954,000 income tax benefit on pre-tax loss of $1.2 million with an effective tax rate of 82% in 1999 compared to an income tax benefit of $15.1 million on pre-tax loss of $39.5 million with an effective tax rate of 38% in 1998. During 1999, the Company recorded an income tax provision for its Canadian operations with an effective tax rate of 7% which was offset by an income tax benefit for its U.S. operations with an effective tax rate of 28%, resulting in an overall effective tax rate of 82%. XI-19 Liquidity and Capital Resources As of December 31, 2000, the Company had working capital of $9.0 million as compared to $3.6 million at December 31, 1999. Cash provided by operating activities was $33.2 million, $10.6 million and $10.7 million in 2000, 1999 and 1998, respectively. The Company's total capital expenditures were $8.2 million, $3.3 million and $19.4 million for 2000, 1999 and 1998, respectively. In 2000, the Company spent $7.1 million related to exploration and development and $579,000 related to acquisitions of oil and gas properties. During 1999, the Company spent $2.6 million related to exploration and development and $.4 million related to acquisitions. In 1998, the Company spent $11.6 million related to exploration and development and $4.8 million related to acquisitions. Sales of oil and gas properties totaled $.2 million, nil, and $2.8 million in 2000, 1999 and 1998, respectively. In June 1997, the Company entered into a $50 million five-year revolving credit agreement with the Toronto-Dominion Bank, the agent, and the Bank of Nova Scotia. On June 30, 1997, the Company was advanced $13.0 million to fund an acquisition of producing properties completed in early July 1997 and to fund certain debt repayments. During 1998, the Company borrowed $12.0 million to fund additional acquisitions and other debt repayments. At December 31, 1999, the Company had a total of $27.0 million outstanding under the revolver and $3,850,000 available based on the current borrowing base, as defined, subject to certain limitations. The facility was amended in June 1998 to extend the initial five-year term an additional year to July 1, 2003 with quarterly borrowing base amortization beginning September 30, 2001. The borrowings can be funded by either Eurodollar loans or Prime loans. The interest rate on the borrowings is equal to an interest rate spread plus either the Eurodollar rate or the Prime 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 1-3/8% to 2% on Eurodollar loans and 3/8% to 1% on Prime loans. The Company's average interest rate under this facility was approximately 8.4% through July 21, 2000, which was the date this facility was terminated. In June 2000, the revolving credit agreement was amended to increase the current borrowing base to $40 million and change the termination date to July 31, 2000, pending a new loan agreement between Toronto-Dominion, as agent, and the Company. The new loan agreement was successfully completed in July 2000 (see next paragraph). Also in June 2000, the Company paid off the Series B fixed rate notes, using available capital and borrowings under the revolving credit agreement. Early termination payments required by the Series B agreement and remaining unamortized debt costs were expensed and are reflected in the financial statements as an extraordinary item of $385,000, less applicable taxes of $143,000. 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 December 31, 2000, the Company had a total of $28,500,000 outstanding under the revolver and $29,500,000 available based on the current borrowing base, as defined, subject to certain limitations. From July 21, 2000, the date of inception of this facility, through December 31, 2000, the weighted average interest rate under this facility was approximately 8.3%. The Company's Canadian subsidiary redeemed its redeemable preferred stock on August 9, 1994 for $7.0 million and simultaneously issued $7.0 million in nonrecourse long-term notes payable (Nonrecourse Notes Payable) with similar financial terms. At December 31, 2000, the nonrecourse long-term notes payable balance was $2.7 million, of which $1,194,000 was classified as "current." 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 XI-20 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. Possible Merger with Southern Mineral As indicated in Note 11 to the financial statements and Part I, Item 1, "Exploration and Development Activity", PetroCorp has entered into an agreement to merge with Southern Mineral Corporation. Funds needed to complete this transaction will be provided by cash on hand and borrowings under existing lines of credit. Subsequent to the signing of the merger agreement, PetroCorp purchased shares of Southern Mineral common stock via open-market and negotiated transactions. As of March 31, 2001, PetroCorp had acquired 738,836 shares of Southern Mineral stock at an average price of $4.21 per share. As a result, PetroCorp currently owns 6% of the outstanding shares of Southern Mineral stock. Year 2000 Issues PetroCorp had no Year 2000 computer problems. Minimal costs were expended in this area. Item 7A. Quantitative and Qualitative Disclosure 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. In 2000, the Company entered into swap transactions in an effort to lock in a portion of higher oil and gas prices. The impact of hedging transactions on 2000 financial results was a net reduction of revenues by $1,097,000. No contracts were outstanding as of December 31, 2000. No hedge transactions were in place during 1999 and 1998. Interest Rate Risk Total debt at December 31, 2000, included no fixed-rate debt. The Company has elected to use only variable rate financing, therefore the Company has limited control over interest rate changes, which may adversely affect the Company's results of operations and cash flows. See Note 5 to the Consolidated Financial Statements for information regarding future maturities of the Company's debt. Foreign Currency Exchange Rate Risk The Company conducts a significant portion of its business in the Canadian dollar and is therefore subject to foreign currency exchange rate risk on cash flows related to sales, expenses, financing and investing transactions. Exposure from market rate fluctuations related to activities in Canada, where the Company's functional currency is the Canadian dollar, is not material at this time. Item 8.

XI-24 REPORT OF INDEPENDENT ACCOUNTANTS To the Board of Directors and Shareholders of PetroCorp Incorporated In our opinion, the accompanying consolidated balance sheets and the related consolidated statements of operations, shareholders' equity and cash flows present fairly, in all material respects, the financial position of PetroCorp Incorporated and its subsidiaries (the "Company") at December 31, 2000 and 1999, and the results of their operations and their cash flows for each of the three years in the period ended December 31, 2000, in conformity with accounting principles generally accepted in the United States of America. These financial statements are the responsibility of the Company's management; our responsibility is to express an opinion on these financial statements based on our audits.

XI-29 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS December 31, 2000, 1999 and 1998 1. Summary of Accounting Policies General PetroCorp Incorporated, a Texas corporation, is engaged in the acquisition, exploration, development, and the production and sale of crude oil and natural gas in North America. The terms "PetroCorp" and "Company" refer to PetroCorp Incorporated and its subsidiaries. PetroCorp operates in Canada through its wholly-owned Canadian subsidiaries as follows: PCC Energy Inc. (PCC Inc.), PCC Energy Limited and PCC Energy Corp. Principles of Consolidation The accompanying consolidated financial statements include the accounts of Petrocorp Incorporated and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated. Use of Estimates The preparation of financial statements in conformity with generally accepted accounting principles requires the Company to make estimates and assumptions that affect the amounts reported in the financial statements and the accompanying notes. Actual results may differ from such estimates. In addition, the oil and gas reserve data and the deferred tax asset include significant estimates which, in the near term, could materially differ from the amounts ultimately realized. Property, Plant and Equipment The Company follows the full cost method of accounting for oil and gas properties whereby all productive and nonproductive exploration and development costs incurred for the purpose of finding oil and gas reserves are capitalized. Such capitalized costs include lease acquisition, geological and geophysical work, delay rentals, drilling, completing and equipping oil and gas wells, together with internal costs directly attributable to property acquisition, exploration and development activities. No gains or losses are recognized upon the sale or other disposition of oil and gas properties, except in unusually significant transactions. The costs of the Company's oil and gas properties, including estimated future development and dismantlement costs, are depreciated on a country-by- country basis using a composite unit-of-production rate. An additional valuation adjustment is made on a country-by-country basis if net capitalized costs of the Company's oil and gas properties exceed the capitalization ceiling, which is calculated on a quarterly basis as the sum of (1) the present value (10%) of future net revenues from estimated production of proved oil and gas reserves plus (2) the lower of cost or estimated fair value of the unproved properties, less (3) the related income tax effects. At December 31, 1998, the Company's net capitalized costs of its U.S. oil and gas properties exceeded the capitalization ceiling by $21,168,000 resulting in a pre-tax valuation adjustment of $33,600,000. Such valuation adjustment is reflected in the Company's results of operations for the year ended December 31, 1998. There was no valuation adjustment for the years ended December 31, 2000 and 1999. Plant and related facilities, consisting principally of a gas processing plant in Alberta, Canada, are being depreciated on a straight-line basis over the remaining estimated useful life. Other property and equipment are depreciated by the straight-line method at rates based on the estimated useful lives of the assets ranging from five to ten years. Revenue Recognition Revenues from the sale of petroleum produced are recognized upon the passage of title, net of royalties and net profits royalty interests. XI-30 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) December 31, 2000, 1999 and 1998 Revenues from natural gas production are recorded using the sales method, net of royalties and net profits interests, which may result in more or less than the Company's share of pro-rata production from certain wells. The Company estimates its balancing position to be approximately $277,000 (173,000 mcf) on underproduced properties and approximately $326,000 (204,000 mcf) on overproduced properties. When sales volumes exceed the Company's entitled share and the overproduced balance exceeds the Company's share of the remaining estimated proved natural gas reserves for a given property, the Company records a liability. At December 31, 2000 and 1999, the Company included $53,000 (33,000 mcf) and $40,000 (26,000 mcf) respectively, in accrued liabilities with respect to overproduced imbalances. The Company's policy is to expense the pro- rata share of lease operating costs from all wells as incurred. Such expenses relating to the balancing position on wells in which the Company has imbalances are not significant. Revenues from plant processing are recognized at the time associated natural gas is processed. Other revenues include fees associated with the Company's U.S. gathering system and from the sale of sulfur in Canada. Accounts Receivable Accounts receivable relate primarily to sales of oil and gas and amounts due from joint-interest partners for expenditures made by the Company on behalf of such partners. The Company reviews the financial condition of potential purchasers and partners prior to signing sales or joint-interest agreements. At December 31, 2000 and 1999, the Company's allowance for doubtful accounts receivable was not significant. Income Taxes The Company utilizes the asset and liability method under which deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Foreign Currency Translation The "functional currency" for translating the Company's Canadian accounts is the Canadian dollar. Assets and liabilities are translated into the reporting currency at the rate of exchange in effect at the balance sheet date while revenues, expenses, gains and losses are translated at the average exchange rate for the period. The resulting translation adjustments are accumulated in the other comprehensive loss component of shareholders' equity. Foreign currency transaction gains and losses are recognized currently. For the years ended December 31, 2000, 1999 and 1998, the Company recognized foreign currency transaction losses of $98,000, $22,000 and $2,000, respectively. Cash Equivalents For purposes of the consolidated statement of cash flows, the Company considers all highly liquid debt instruments purchased with a maturity date of three months or less at the date of purchase to be cash equivalents. Cash and cash equivalents are not insured above FDIC limits, which subjects the Company to credit risk. Hedging Activities To reduce the impact of fluctuations in the market prices of oil and natural gas, the Company periodically utilized hedging strategies such as futures transactions or swaps to hedge the price of a portion of its future oil XI-31 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) December 31, 2000, 1999 and 1998 and natural gas production. Results of these hedging transactions are reflected in oil and natural gas sales in the month of hedged production. At December 31, 2000, 1999 and 1998, the Company had no such hedging or derivative contracts. In 2000, the impact of hedging transactions was a net reduction of revenues by $1,097,000. No hedging transactions occurred in 1999 or 1998. Other 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, is effective January 1, 2001 for the Company. SFAS 133 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 hedge transactions the nature and type of hedge will be disclosed. Based on the types of hedging transactions historically employed, the Company does not anticipate that the adoption of SFAS 133 will have a significant effect on the results of operations or financial position. 2. Restructuring As part of a restructuring plan, on August 3, 1999, PetroCorp's Board of Directors entered into a Management Agreement with its largest shareholder, Kaiser-Francis Oil Company ("Kaiser-Francis"), under which Kaiser-Francis provides management, technical, and administrative support services for all PetroCorp operations in the United States and Canada. As a result of the restructuring, fifty-two employees were terminated in 1999 with one employee terminated in 2000. Several employees elected to defer receipt of their termination benefits until 2000. The Houston, Oklahoma City and Calgary offices were closed but the Company was still liable under the lease agreements. In the second quarter of 2000, the Company was able to find a replacement lessee for some of the idle office space earlier than anticipated. The company recorded restructuring costs of $3,643,000 during 1999. Included in the costs are employee termination costs of $2,371,000, $807,000 in nonrefundable office lease discontinuance, $363,000 in investment banking and legal costs, and $102,000 in other related costs. As of December 31, 1999, $2,161,000 of the restructuring costs are included in accrued liabilities. The following table shows the change in accrued restructuring costs during 2000: Expenditures Balance at charged Changes Balance at December 31, against in December 31, 1999 accrual estimates 2000 ------------ ------------ --------- ------------ Employee termination costs... $1,341,000 $1,341,000 $ -- $ -- Office lease discontinuance and other related costs............... 820,000 305,000 (445,000) 70,000 ---------- ---------- --------- ------- $2,161,000 $1,646,000 $(445,000) $70,000 ========== ========== ========= ======= XI-32 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) December 31, 2000, 1999 and 1998 3. Comprehensive Income The Company follows SFAS No. 130, "Reporting Comprehensive Income." This Statement establishes requirements for reporting comprehensive income and its components which includes the Company's foreign currency translation adjustment. The Company's comprehensive income (loss) for the years ended December 31, 2000, 1999 and 1998 are as follows (amounts in thousands): Years ended December 31, ------------------------- 2000 1999 1998 ------- ------ -------- Net income (loss)............................. $12,818 $ (206) $(24,395) Foreign currency translation..................

Oil and gas property depreciation, depletion and amortization for the years ended December 31, 2000, 1999 and 1998 was $7,947,000, $8,138,000 and $14,961,000 , respectively. Depreciation, depletion and amortization per equivalent Mcf (using a Mcf-to-barrel conversion factor of 6 to 1) for the years ended December 31, 2000, 1999 and 1998 was $0.85, $0.85 and $1.62, respectively, for U.S. operations and $0.61, $0.50 and $0.53, respectively, for Canadian operations. The total composite rates were $0.74, $0.69 and $1.16 for the years ended December 31, 2000, 1999 and 1998, respectively. 5.

Series A and Series B Senior Notes On July 29, 1993, the Company entered into the Note Purchase Agreement with subsidiaries of CIGNA Corporation and USF&G Corporation together with certain other insurance companies to refinance existing notes. The final payment of $875,000 on the Series A Note was made in June 1999 to an affiliate. During 2000, the Series B Notes were paid off prior to their maturity date. The loss from extinguishment of the Series B Notes is shown as an extraordinary item. Bank Debt On June 26, 1997, the Company entered into a $50 million, five-year revolving credit agreement with the Toronto-Dominion Bank (TD Bank), the agent, and the Bank of Nova Scotia. The facility was amended in June 1998 and July 1999 to extend the initial five-year term an additional year to July 1, 2003 with quarterly borrowing base amortization beginning September 30, 2001. The borrowings can be funded by either Eurodollar loans or Prime loans. The interest rate on the borrowings is equal to an interest rate spread plus either the Eurodollar rate or the Prime 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 ranged from 1 3/8% to 2% on Eurodollar loans and 3/8% to 1% on Prime loans. In June 2000, the revolving credit agreement was amended to increase the current borrowing base to $40 million and change the termination date to July 31, 2000, pending a new loan agreement between Toronto-Dominion, as agent, and the Company. The new loan agreement was successfully completed in July, 2000 (see next paragraph). Also in June 2000, the Company paid off the Series B fixed rate notes, using available capital and borrowings under the revolving credit agreement. Early termination payments required by the Series B agreement and remaining unamortized debt costs were expensed and are reflected in the financial statements as an extraordinary item of $385,000, less applicable taxes of $143,000. 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 December 31, 2000, the weighted average interest rate under this facility was approximately 9.4%. 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. Nonrecourse Notes Payable On December 12, 1991, the Company (through its Canadian subsidiary, PCC Inc.) acquired an interest in certain oil and gas properties and related gas processing facilities located in the Hanlan-Robb area in western Alberta, Canada. The Company used the proceeds from the issuance of redeemable preferred stock of PCC Inc. to partially fund the acquisition. The holders of the preferred stock also separately and concurrently acquired an interest in the same oil and gas properties as the Company. XI-34 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) December 31, 2000, 1999 and 1998 On August 9, 1994, PCC Inc. entered into agreements whereby PCC Inc. redeemed the remaining shares of its redeemable preferred stock for $7,034,000. Simultaneously, PCC Inc. issued $7,034,000 in nonrecourse long-term notes payable (the Nonrecourse Notes Payable) to the previous holders of the preferred stock with financial terms similar to the redeemable preferred stock. Consistent with the redeemable preferred stock, the Nonrecourse Notes Payable are denominated in Canadian dollars. In 2000, 1999 and 1998, the Company issued $525,000, $238,000 and $846,000 of additional notes, respectively, as provided under the provisions of the agreements to finance the company's portion of plant capital additions. Interest accrues and is payable on a quarterly basis at a rate of 15% per annum. In addition, redemptions are required to be made quarterly, based on a fixed schedule through December 31, 2002. Interest and redemption payments are made only to the extent there are sufficient cash proceeds from production and sale of oil and gas reserves related to the interest in the Hanlan-Robb assets acquired by the holders of the Nonrecourse Notes Payable. To the extent interest and redemptions exceed such cash proceeds, the excess amount is carried forward to the next quarter. At December 31, 2000 and 1999, unpaid interest and redemptions totaled $503,000 and $449,000, respectively. 6. Income Taxes The components of income (loss) before income taxes for the years ended December 31, 2000, 1999 and 1998 consisted of the following (amounts in thousands): 2000 1999 1998 ------- ------- -------- United States operations................... $ 9,834 $(4,191) $(40,630) Canadian operations........................ 13,335 3,031 1,121 ------- ------- -------- $23,169(A) $(1,160) $(39,509) ======= ======= ======== The provision (benefit) for income taxes consists of the following (amounts in thousands): 2000 1999 1998 ------- ------- -------- Deferred: Federal................................... $ 3,488 $(1,090) $(14,348) State..................................... 317 (65) (820) Canadian.................................. 807 201 54 ------- ------- -------- 4,612 (954) (15,114) Current: Canadian.................................. 5,497 -- -- ------- ------- -------- $10,109(A) $ (954) $(15,114) ======= ======= ======== - -------- (A) Excludes extraordinary loss of $385,000 and related taxes of $143,000.

Regular tax NOL carryforwards and alternative minimum tax NOL carryforwards begin to expire in 2009. Realization of the deferred tax asset is dependent on generating sufficient taxable income prior to expiration of loss carryforwards. Although realization is not assured, management believes it is more likely than not that the deferred tax asset will be realized. The amount of the deferred tax asset considered realizable, however, could be reduced in the near term if estimates of future taxable income during the carryforward period are reduced. Additionally, certain future changes in the Company's shareholders may impose restrictions under Section 382 of the Internal Revenue Code on the annual utilization of its net operating loss carryforwards.

All of these options are exercisable as of December 31, 2000. XI-37 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) December 31, 2000, 1999 and 1998 In 1997, the Company established the 1997 PetroCorp Non-Employee Director Stock Option Plan (the Director Option Plan) for the benefit of the Company's Board of Directors. This plan allows up to 75,000 option shares to be granted. The Director Options were fully vested and exercisable at the date of grant. The following table summarizes these options: Weighted Average Exercise Options Price ------- ---------------- Outstanding at December 31, 1997................. 25,000 $8.63 Granted........................................ 6,000 $8.25 Forfeited...................................... -- -- Exercised...................................... -- -- ------ Outstanding at December 31, 1998................. 31,000 $8.55 Granted........................................ 6,000 $6.75 Forfeited...................................... -- -- Exercised...................................... -- -- ------ Outstanding at December 31, 1999................. 37,000 $8.26 Granted........................................ -- -- Forfeited...................................... -- -- Exercised...................................... -- -- ------ Outstanding at December 31, 2000................. 37,000 $8.26 ====== As of December 31, 2000, the weighted average remaining contractual life of the outstanding options under the Director Option Plan was 7.1 years and the exercise prices ranged from $6.75 to $8.63. In 2000, the Company established the 2000 Stock Option Plan for the benefit of employees and the Company's Board of Directors. Employee options vest one year from date of grant and director options vest six months from the date of grant. This plan allows up to 600,000 option shares to be granted. The following table summarizes these options: Weighted Average Exercise Options Price ------- ---------------- Outstanding at December 31, 1999................. -- -- Granted........................................ 106,650 $6.34 Forfeited...................................... -- -- Exercised...................................... -- -- ------- Outstanding at December 31, 2000................. 106,650 $6.34 ======= As of December 31, 2000, the weighted average remaining contractual life of the outstanding options under the 2000 Stock Option Plan was 9.2 years. Of the outstanding options, 5,000 were exercisable at year end with an average remaining contractual life of 9.4 years. At December 31, 2000, exercise prices ranged from $6.13 to $7.06. Stock options under all three plans expire ten years from the date of grant and exercise price equals market value on the grant date. XI-38 PETROCORP INCORPORATED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued) December 31, 2000, 1999 and 1998 The Company adopted SFAS No. 123, "Accounting for Stock Based Compensation," effective July 1, 1996. While SFAS No. 123 encourages entities to adopt the fair value based method of accounting for their stock-based compensation plans, the Company has elected to continue to utilize the intrinsic value method under Accounting Principles Board (APB) Opinion No. 25, "Accounting for Stock Issued to Employees." Compensation expense has been recognized for these stock-based compensation plans for any grants to individuals who do not meet the definition of employee. Had compensation cost for the 2000 Stock Option Plan and the Director Option Plan been determined based upon the fair value at the grant date for awards under the plans, consistent with the methodology prescribed under SFAS No. 123, the Company's 2000, 1999 and 1998 net income and earnings per share would have been reduced by approximately $330,000, $17,000 and $16,000, or $0.04, nil and nil per share, respectively. The fair value of the options granted during 2000, 1999 and 1998 were $432,000, $27,000 and $26,000, respectively, on the dates of grants using the Black-Scholes option-pricing model with the following assumptions: 2000 1999 1998 --------- ---- ---- Weighted average life, in years..................... 10 10 10 Risk-Free interest rate............................. 6.0%-6.5% 6.1% 5.8% Expected Volatility................................. 41% 46% 26% Expected Dividend Rate None None None Effective January 1, 1993, the Company established a savings plan, which is available to eligible employees and qualifies as a deferred compensation plan under Section 401(k) of the Internal Revenue Code. The Company matches employee contributions for an amount up to 6% of each employee's salary. The Company's contributions to the plan, which are charged to expense, totaled $100,000, $198,000 and $192,000 in 2000, 1999 and 1998, respectively.

Geographic Area Information The principal business of the Company is oil and gas, which consists of the exploration, development, acquisition, exploitation and operation of oil and gas properties and the production and sale of crude oil and natural gas in North America. Pertinent information with respect to the Company's oil and gas business is presented in the following table (amounts in thousands): United General States Canada Corporate Total ------- ------- --------- -------- 2000: Revenues.......................... $23,588 $20,985 $ -- $ 44,573 Income (loss) from operations..... 12,353 14,402 (1,084)(A) 25,671 Depreciation, depletion and amortization..................... 5,178 4,293 -- 9,471 Capital expenditures.............. 1,730 6,459 -- 8,189 Long-lived assets at December 31.. 44,259 36,931 242 81,432 1999: Revenues.......................... $15,565 $11,561 $ -- $ 27,126 Income (loss) from operations 5,045 5,607 (8,400)(B) 2,252 Depreciation, depletion and amortization..................... 5,746 3,714 446 9,906 Capital expenditures.............. 1,043 2,212 -- 3,255 Long-lived assets at December 31.. 51,516 36,106 107 87,729 1998: Revenues.......................... $15,911 $ 9,296 $ -- $ 25,207 Income (loss) from operations (35,593)(C) 3,381 (4,840) (37,052) Depreciation, depletion and amortization..................... 12,511 3,698 359 16,568 Capital expenditures.............. 11,673 7,653 68 19,394 Long-lived assets at December 31.. 54,335 36,668 308 91,311 - -------- (A) Net of $445 restructuring cost credits. (B) Includes $3,643 of restructuring costs. (C) Includes a $33,600 oil and gas property valuation adjustment. The following table reflects purchasers which accounted for more than 10% of the Company's oil and gas revenues: 2000 1999 1998 ---- ---- ---- Pan-Alberta Gas Ltd........................................... 19% 18% 23% EOTT Energy Operating Limited Partnership..................... -- 11% 10% Conoco Inc.................................................... -- -- 10% Engage Energy LP.............................................. 27% 17% -- During 1999 and prior, the majority of the Company's Canadian gas was dedicated under long-term contracts to Pan-Alberta Gas Ltd., a major Canadian aggregator. However, as part of a legal settlement effective December 31, 1998, approximately 50% of PetroCorp's dedicated gas volumes have been released from the Pan-Alberta contracts. These released volumes are now sold on the spot market at prevailing prices. The Company does not believe the loss of any purchaser would have a material adverse effect on its financial position since the Company believes alternative sales arrangements could be made on relatively comparable terms.

Fair Value of Financial Instruments The following information discloses the fair value of the Company's financial instruments in accordance with SFAS 107, "Disclosures About Fair Value of Financial Instruments" (amounts in thousands): Carrying Fair Amount Value -------- ------- 1999: Long-term debt: Series B, 7.55% senior notes........................ $17,350 $17,811 The carrying amounts approximate fair value for the Company's cash and cash equivalents, accounts receivable, accounts payable, and bank debt. Due to the nature and terms of the Nonrecourse Notes Payable, the Company believes that it is not practicable to estimate the fair value. The Company estimated the fair value of the Series B, 7.55% senior notes using discounted cash flow analysis based on 115 basis points above year end LIBOR rates. 11. Commitments and Contingencies The Company has entered into operating lease agreements with noncancelable terms in excess of one year for office space. Future minimum lease payments are $99,000 and $58,000 for the years ending December 31, 2001 and 2002, respectively with no payments after that time. Future minimum sublease income with noncancelable terms in excess of one year for office space are $60,000 and $35,000 for the years ending December 31, 2001 and 2002. Total rental expense for office space for the years ended December 31, 2000, 1999 and 1998 was $111,000, $583,000 and $560,000, respectively. Accrued restructuring costs include $70,000 of office lease discontinuance costs at December 31, 2000. On December 22, 2000, the Company and Southern Mineral Corporation (Southern Mineral) announced they have executed a definitive agreement regarding Southern Mineral's merger into PetroCorp. In the merger, expected to close in the second quarter of 2001, shareholders of Southern Mineral will receive consideration of $4.71 per share in cash or, at their election, PetroCorp common stock or a combination of cash and stock, subject to certain adjustments. The merger will be accounted for under the purchase method of accounting. There are other claims and actions pending against the Company. In the opinion of management, the amounts, if any, which may be awarded in connection with any of these claims and actions would not be material to the Company's consolidated financial position or results of operations. 12. Related Party Transactions The Company has engaged an engineering consulting company to procure certain services and equipment pertaining to its Canadian operations. The consulting company solicits bids from various vendors in order to obtain competitive pricing. During 2000, 1999 and 1998, the consulting company procured nil, $45,000 and $236,000 from an equipment supplier partly owned by a director of the Company's Canadian subsidiaries who is a relative of the Company's previous Chief Executive Officer. The Company is a joint-interest owner in a project operated by Kaiser- Francis Oil Company, a shareholder. During 2000, 1999 and 1998, the Company remitted $154,000, $95,000 and $181,000, respectively, to Kaiser-Francis as payment of the Company's share of the joint operation. During 2000, the Company remitted $2,076,000 to Kaiser-Francis for management fees and cost reimbursements under the Management Agreement (see Note 2). Amounts payable to Kaiser-Francis at December 31, 2000 and 1999 were $22,055 and $100,000, respectively.

The resulting future net cash flows were discounted using a rate of 10% per annum. The standardized measure of discounted future net cash flow amounts contained in the following tabulation do not purport to represent the fair market value of oil and gas properties. No value has been given to unproved properties. There are significant uncertainties inherent in estimating quantities of proved reserves and in projecting rates of production and the timing and amount of future costs. Future realization of oil and gas prices over the remaining reserve lives may vary significantly from current prices. In addition, the method of valuation utilized, based on current prices and costs and the use of a 10% discount rate, is not necessarily appropriate for determining fair value. The average prices used in determining future cash inflows for natural gas and oil as of December 31, 2000, were $9.19 per Mcf and $27.16 per barrel, respectively. These prices were based on the adjusted cash spot price for natural gas and oil at December 31, 2000.

Undertakings. (a) The undersigned Registrant hereby undertakes: (1) To file, during any period which offers or sales are being made, a post-effective amendment to this Registration Statement; (i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933; (ii) To reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement; (iii) To include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement. Provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) do not apply if the Registration Statement is on Form S-3, Form S-8 or Form F-3, and the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the SEC by the Registrant pursuant to Section 13 or 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the Registration Statement. (2) That, for the purpose of determining any liability under the Securities Act of 1933, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering. PART II-4 (b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant's annual report pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (c) (1) The undersigned Registrant hereby undertakes as follows: that prior to any public reoffering of the securities registered hereunder through use of a prospectus which is a part of this Registration Statement, by any person or party who is deemed to be an underwriter within the meaning of Rule 145(c), the issuer undertakes that such reoffering prospectus will contain the information called for by the applicable registration form with respect to reofferings by persons who may be deemed underwriters, in addition to the information called for by the other Items of the applicable form. (2) The Registrant undertakes that every prospectus: (i) that is filed pursuant to paragraph (1) immediately preceding, or (ii) that purports to meet the requirements of section 10(a)(3) of the Act and is used in connection with an offering of securities subject to Rule 415, will be filed as a part of an amendment to the Registration Statement and will not be used until such amendment is effective, and that, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. (d) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue. (e) The undersigned Registrant hereby undertakes to respond to requests for information that is incorporated by reference into the Proxy Statement/Prospectus pursuant to Items 4, 10(b), 11, or 13 herein, within one business day of receipt of such request, and to send the incorporated documents by first class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the Registration Statement through the date of responding to the request. (f) The undersigned Registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the Registration Statement when it became effective. PART II-5 SIGNATURES Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-4 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Tulsa, State of Oklahoma, on the 28th day of March, 2001.
