P-4 Notes to Unaudited Pro Forma Combined Financial Information (Dollars in thousands) 1. Basis of Presentation The pro forma financial information presents the combination using the purchase method of accounting and reflects the total number of common units of Dorchester Minerals, L.P. outstanding upon the consummation of the combination of 27,040,431. Dorchester Hugoton is deemed to be the acquiror because its depository receipt holders are the ownership group that received the largest ownership interest in Dorchester Minerals, L.P. Accordingly, the assets of Republic, the Republic ORRIs and Spinnaker are adjusted to fair value in the pro forma balance sheet. For accounting purposes, the fair value (new basis) of the assets of Republic, the Republic ORRIs and Spinnaker is based on the fair value of Dorchester Hugoton and the share of the total common units of Dorchester Minerals, L.P. that the partners of Republic, the Republic ORRIs and Spinnaker received, as follows: Market capitalization of Dorchester Hugoton at January 31, 2003 based on the closing price of $16.08 per common unit................... $174,515 Less cash distributed to Dorchester Hugoton unitholders prior to the combination transaction.......... (20,614) -------- Estimated fair value of Dorchester Hugoton assets contributed to Dorchester Minerals, L.P............................... $153,901 ======== The Dorchester Hugoton unitholders received 39.73% of the common units of Dorchester Minerals, L.P. in exchange for their interest in Dorchester Hugoton, which results in a valuation of Dorchester Minerals, L.P. of $387,367. The fair market value of the assets of Republic, the Republic ORRIs and Spinnaker were determined based on the percentage interests that their partners received in Dorchester Minerals, L.P., as follows: Percentage Fair Value Interest of Assets --------- ---------- Republic.................................. 5.87% $ 22,754 Republic ORRIs............................ 34.64% 134,168 Spinnaker................................. 19.76% 76,544 --------- $233,466 ========= 2. Pro Forma Adjustments Balance sheet adjustments: (a) Eliminate intercompany receivables and payables and the effect of intercompany transactions on property and equipment. (b) Eliminate assets and liabilities that were not transferred to Dorchester Minerals, L.P. (c) Adjust historical book values of property and equipment of Republic, the Republic ORRIs, and Spinnaker to fair value, as follows: P-5 Purchase accounting fair value.............................. $233,466 Historical cost: Republic, after elimination of intercompany transaction $ 2,754 Republic ORRIs......................................... 26,951 Spinnaker.............................................. 11,417 41,122 ------- ------- $192,344 ======== Allocation: Property and equipment................................. $131,634 Accumulated depreciation, depletion and amortization........................................ 60,710 -------- $192,344 ======== (d) Adjust equity accounts to reflect capital structure of Dorchester Minerals, L.P. Statement of operations adjustments: ----------------------------------- (a) Eliminate intercompany transactions and their effect on depletion. (b) Reflect the income and expenses of Dorchester Hugoton as a 96.97% net profits interest. Under the net profits interests agreement, certain costs and expenses previously incurred by Dorchester Hugoton are the obligations of Dorchester Minerals Operating LP, and Dorchester Minerals, L.P. will retain a 96.97% net profits interest. Accordingly, adjustments have been made to reduce expenses and revenues as follows: For the Nine Month For the Year Period Ended Ended September 30, 2002 December 31, 2001 ------------------ ----------------- Expenses Operating expenses.......................... $2,058 $3,160 Production taxes............................ 629 1,721 General and administrative expenses......... 339 461 Other deductions Production payment.......................... -- 566 Other....................................... 35 272 ------ ------ $3,061 $6,180 ====== ====== The effect on revenue is as follows: Dorchester Hugoton historical revenues: Natural gas sales............................... $12,761 $27,153 Other revenue................................... 96 192 ------- ------- 12,857 27,345 Deduct costs and expenses.......................... (3,061) (6,180) ------- ------- 9,796 21,165 Net profits interest............................... x 96.97% x 96.97% ------- ------- Pro forma net profits interest revenue............. $ 9,499 $20,524 ======= ======= P-6 (c) Adjust depreciation, depletion, and amortization based on the new basis of oil and gas properties. (d) Eliminate income and expense related to assets and liabilities of Dorchester Hugoton that were not transferred to Dorchester Minerals, L.P.. (e) Eliminate nonrecurring transaction costs. (f) Eliminate management fees. (g) Increase general and administrative expenses for reimbursable costs incurred by Dorchester Minerals Operating LP. 3. Severance Payments Dorchester Hugoton had a severance policy pursuant to which payments in the approximate amount of $2.7 million have been made by Dorchester Hugoton to its employees and general partners upon consummation of the Combination. These payments were not an obligation of Dorchester Minerals, L.P. and are not included as a liability or an expense in the pro forma financial statements. 4. Pro Forma Information on Oil and Gas Operations The pro forma reserve information set forth below assumes the combination transactions were completed on January 1, 2001. There are many uncertainties inherent in estimating reserve quantities, and in projecting future production rates and the timing of future development expenditures. Accordingly, estimates are subject to change as additional information becomes available. Revisions of estimates can have a significant impact on the results. Proved oil and natural gas reserves are the estimated quantities of crude oil, condensate, natural gas and natural gas liquids that geological and engineering data demonstrate with reasonable certainty to be recoverable in future years from known reservoirs under existing economic conditions. Proved developed oil and gas reserves are those reserves expected to be recovered through existing equipment and operating methods. All reserves are located in the United States.
