F-4 UNIT CORPORATION AND SUBSIDIARIES LOWER - 48 DIVISION A DIVISION OF PARKER DRILLING COMPANY NORTH AMERICA, INC. NOTES TO FINANCIAL STATEMENTS Note 1 - Summary of Significant Accounting Policies - --------------------------------------------------- Organization - The Lower-48 Division ("Division") is a division of Parker Drilling Company North America, Inc. ("PDCNA"). Stockholders of PDCNA are Parker USA Drilling, Inc. (50%), Parker Drilling USA, Ltd. (40%) and Universal Rig (10%). The subsidiaries who own PDCNA are wholly owned subsidiaries of Parker Drilling Company ("Parent Company"). Basis of Presentation - The accompanying financial statements have been prepared to present the assets and liabilities and related revenues and direct operating expenses of the Division and also include allocated general and administrative expenses (Note 2) and income taxes (Note 3). The financial information included herein may not necessarily reflect the financial position, results of operation or cash flows of the Division if it had been a separate stand alone company. Division Equity - Division equity is comprised of intercompany accounts and historical retained earnings. The intercompany accounts include transactions related to capital assets transferred in or out of the Division, cash receipts and cash disbursements and allocated general and administrative expenses. The Division does not maintain a separate cash account, all cash transactions are received or disbursed by the Parent. Changes in division equity were as follows: Year Ten Months Ten Months Ended Ended Ended August 31, June 30, June 30, 1998 1999 1998 ---------- ---------- ---------- (Unaudited) (In thousands) Division Equity - Beginning of Period $ 17,461 $ 17,533 $ 17,461 Net Income (Loss) 625 (1,463) 713 Change in Intercompany Accounts (553) (3,306) (483) ---------- ---------- ---------- Division equity - end of period $ 17,533 $ 12,764 $ 17,691 ========== ========== ========== Drilling Contracts - The Division recognizes revenue and expenses on dayrate contracts as the drilling progresses (percentage-of-completion method) because the Division does not bear the risk of completion of the well. For meterage contracts, the Division recognizes the revenue and expenses upon completion of the well (completed-contract method). F-5 Note 1 - Summary of Significant Accounting Policies (continued) - --------------------------------------------------------------- Property, Plant and Equipment - The Division provides for depreciation of property, plant and equipment primarily on the straight-line method over the estimated useful lives of the assets after provision for salvage value. In the third quarter of fiscal 1998, the Parent Company reviewed the estimated useful life of its land drilling fleet used for financial depreciation purposes. As a result, the estimated life was extended from 10 to 15 years with a five percent salvage value for most of the major rig components, resulting in a reduction in the Division's fiscal 1998 depreciation expense of approximately $103,000. The Parent Company's historical experience and a comparison with other firms in the industry indicate that its land drilling equipment has a useful life of at least 15 years. The depreciable lives for certain other equipment, ranging from three to seven years, including drill pipe, were not extended. When properties are retired of otherwise disposed of, the related cost and accumulated depreciation are removed from the accounts and any gain or loss is included in operations. Management periodically evaluates the Division's assets to determine if they are not in excess of their net realizable value. Management considers a number of factors such as estimated future cash flows, appraisals and current market valued analysis in determining net realizable value. Assets are written down to reflect any decrease in net realizable value below their net carrying value. Substantially all of the Division's property, plant and equipment is pledged as collateral on the Parent Company debt. Concentrations of Credit Risk - Financial instruments which potentially subject the Division to concentrations of credit risk consist primarily of trade receivables with a variety of national and international oil and natural gas companies. The Division generally does not require collateral on its trade receivables. Such credit risk is considered by management to be limited, due to the larger number of customers comprising the Division's customer base. In fiscal year 1998, three customers accounted for 50% of revenues. At August 31, 1998, accounts receivable from one of these customers was $1,394,000. Accounting Estimates - The preparation of financial statements in conformity with generally accepted accounting principles requires 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. F-6 Note 2 - Transactions with Related Parties - ------------------------------------------- The Parent Company provides management and administrative services to the Division and charges that part of its administrative overhead allocable to such activities to the Division. During the year ended August 31, 1998 and the ten months ended June 30, 1999 and 1998, the Parent Company allocated administrative overhead to the Division of $5,907,000, $3,807,000 and $4,923,000, respectively. The overhead allocation is based on the number of rig operating days of the Division multiplied by the overhead cost per day, which is derived by dividing the total allocable overhead by the total rig operating days. In addition, substantially all accounts receivable and accounts payable are processed and collected or paid by the Parent Company. When the Parent Company records a trade account payable on behalf of the Division, a corresponding account receivable is recorded in the intercompany (division equity) account. Due to the difficulty in determining the specific amount of trade accounts payable and accrued liabilities attributable to the Division included in division equity, management has reclassified $756,000 and $2,851,000 from Division equity to accounts payable and accrued payroll and related employee benefits as an estimate, based on the Parent Company's normal vendor payment policy and workers compensation and health care cost allocable to the Division. Management considers the methods used to make such allocations to be reasonable. The Division's accounts receivable are pledged as collateral on the Parent Company's revolving credit facility. Note 3 - Income Taxes - ---------------------- The Division's taxable income or loss is included in PDCNA's results of operations, which are included in the Parent Company's consolidated income tax returns. For purposes of the statement of operations the Division's federal and state income taxes have been calculated at the combined statutory rate of 38 percent. Note 4 - Contingent Liability - ----------------------------- During April 1997 a well in Louisiana for which PDCNA was the drilling contractor erupted and blew out. Numerous lawsuits have been filed against PDCNA and other parties by individuals living in and around the drilling site alleging damage to property and personal injury. PDCNA anticipates that $250,000 will be paid to satisfy outstanding claims. This amount has been recognized in the financial statements. Note 5 - Subsequent Event - ------------------------- On August 12, 1999, the Parent Company signed a definitive agreement to sell its thirteen domestic Lower-48 land drilling rigs and related equipment and other assets to Unit Corporation for $40 million cash plus one million shares of Unit Corporation common stock. These thirteen land drilling rigs represent all of the drilling rigs owned by the Division. Closing of the transaction is subject to several conditions including securing required governmental approvals, third party consents and Unit Corporation obtaining financing for the cash portion of the purchase price. F-7 Note 6 - Interim Financial Information (Unaudited) - -------------------------------------------------- The interim consolidated financial statements and footnote information presented herein are unaudited, but reflect, in the opinion of management, all adjustments (which include only normal recurring adjustments) necessary for fair presentation of the results for such periods. On September 30, 1999, Parker Drilling Company completed the sale of its thirteen lower - 48 land rigs to Unit Corporation for $40 million cash plus one million shares of Unit Corporation common stock.

P-4 UNIT CORPORATION AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS 1. THE ACQUISITION - ------------------ On September 30, 1999, the Company completed the acquisition of 13 land contract drilling rigs and related equipment (the "Parker Acquisition") from Parker Drilling Company and Parker Drilling Company North America, Inc. (the "Sellers"). Under the terms of the Parker Acquisition, the Sellers received 1,000,000 shares of the Company's common stock valued at $8,138,000 and $40,000,000 in cash. The cash portion of the consideration paid was funded through an offering of 7,000,000 shares of the Company's common stock which closed on September 29, 1999. The net proceeds received by the Company from the offering were $50,435,000. 2. BASIS OF PRESENTATION - ------------------------ The accompanying unaudited Pro Forma Consolidated Condensed Financial Statements are presented to reflect the equity offering and the consummation of the Parker Acquisition. The unaudited Pro Forma Consolidated Condensed Balance Sheet is presented as if the acquisition, accounted for under the purchase method, occurred as of June 30, 1999. The unaudited Pro Forma Consolidated Condensed Statements of Operations are presented as if the acquisition occurred on January 1, 1998 and may not be indicative of the results that would have occurred if the acquisition had been effective on the dates indicated or of the results that may be obtained in the future. The accompanying pro forma financial statements should be read in conjunction with the historical financial statements and notes to financial statements of both Unit Corporation and the Lower - 48 Division ("Division"). 3. PRO FORMA ADJUSTMENTS - ------------------------ The accompanying unaudited Pro Forma Consolidated Condensed Financial Statements include the following adjustments: (a) Adjustments to remove certain assets, liabilities and shareholder's equity of the Division at June 30, 1999 which were not acquired by Unit Corporation. (b) Adjustments to property, plant and equipment yields the purchase price of the acquired assets of $48,138,000. (c) Adjustment records the accrued liabilities incurred by Unit Corporation of $300,000 for its costs incurred during the equity offering. (d) Adjustment to long-term debt represent the proceeds from the equity offering in excess of the cash amount needed for the Parker Acquisition, which proceeds were utilized to reduce the Company's long-term debt. P-5 UNIT CORPORATION AND SUBSIDIARIES NOTES TO UNAUDITED PRO FORMA CONSOLIDATED CONDENSED FINANCIAL STATEMENTS - CONTINUED (e) Adjustments to common stock and additional paid in capital represent the issuance of 7,000,000 shares of common stock from the equity offering to finance the cash portion of the Parker Acquisition and the issuance of 1,000,000 shares of common stock to the Sellers for the stock portion of the Parker Acquisition. The 7,000,000 shares were issued at a price of $7.625 generating gross proceeds of $53,375,000. Underwriting discounts and commissions and Unit Corporation's offering costs totaled $2,940,000 and $300,000, respectively, providing net proceeds to Unit Corporation of $50,135,000. The 1,000,000 shares issued to the Sellers were valued at $8.1375 per share. (f) Adjustment provides depreciation expense computed on the $48,138,000 purchase price of the acquired assets. Depreciation and amortization of drilling equipment was calculated using the units-of-production method based on a useful life of 15 years for the acquired rigs, including a minimum provision of 20 percent of the active rate when the equipment is idle. Depreciation for drill pipe and drill collars was calculated using the composite method which calculates depreciation by footage actually drilled compared to total estimated remaining footage. Depreciation of other property and equipment was computed using the straight-line method over the estimated useful lives of the assets ranging from 3 to 10 years. (g) Historical general and administrative expense from the Division was reversed since they represent allocated corporate overhead from the Parent Company and such costs will not be incurred by Unit Corporation. Unit Corporation's general and administrative expense will increase by approximately $50,000 annually due to the additional expense associated with the increase in office employees required to account for the acquired rigs. (h) The adjustment to interest expense represents reduced interest on $10.4 million of long-term debt paid from excess proceeds from the equity offering. The average interest rate paid by Unit Corporation on bank debt in 1998 and the first six months of 1999 was 7.0 and 6.4 percent, respectively. (i) The adjustment to income tax expense represents the increase in taxes associated with the combined pro forma results of operations based on the statutory (federal and state) tax rate.
