The fair value of PetroCorp common stock used in the pro forma calculations is $9.75 per share, which reflects the average 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 did not exercise prior to the consummation of the merger received 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 March 31, 2001, and, therefore, the net purchase consideration related to warrant and option holders reflected in the purchase price allocation is $1,520,000 and $246,000, respectively. The purchase price allocation is (amounts in thousands): Issuance of common stock $39,120 Net cash to Southern Mineral stockholders (1) 18,669 Assumed liabilities and debt and liabilities incurred 32,782 ------- Total deemed purchase consideration $90,571 ======= (1) The net cash payable to Southern Mineral shareholders was determined as follows: 12,925,317 Southern Mineral shares at $4.71 $ 60,878 81,000 stock options with various exercise prices 246 3,039,737 warrants with net cash rights of $.50 per share 1,520 -------- 62,644 Reduced for dollar equivalent of PetroCorp shares issued, Assuming a $10 per share amount (40,123) Reduced for dollar equivalent of Southern Mineral shares owned by PetroCorp (3,852) -------- $ 18,669 ======== Southern Mineral Estimated Fair Pro Forma Book value Value Adjustment Current assets $ 8,284 $ 8,284 $ -- Property, plant and equipment 72,072 84,839 12,767 Other assets 1,135 858 (277) Current liabilities (8,449) (11,396) (2,947) Debt assumed by PetroCorp (15,880) (15,880) -- Deferred income taxes (6,504) (5,506) (998) -------- -------- ---------- $ 50,658 $ 61,199 $10,541 ======== ======== ========== PETROCORP INCORPORATED NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL STATEMENTS--(CONTINUED) Note: The adjustments of current assets and other assets are to write off the book basis of existing Southern Mineral bank loan cost which is not expected to have ongoing value to PetroCorp. 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 Pro Forma for March 31, 2001 assumes no drawdown of additional long-term debt to complete financing of 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 Pro Forma for March 31, 2001 assumes no drawdown of additional long-term debt to complete financing of transaction, so no additional interest is shown. G To record $300,000 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.
