2 INFORMATION TO BE INCLUDED IN THE REPORT ITEM 2. ACQUISITION OR DISPOSITION OF ASSETS On January 16, 2001, Chesapeake Energy Corporation ("Chesapeake") completed the acquisition of Gothic Energy Corporation ("Gothic") by merging Chesapeake Merger 2000 Corp. into Gothic pursuant to the Agreement and Plan of Merger among the parties dated September 8, 2000, as amended on October 31, 2000. Chesapeake issued a total of 4.0 million common shares in the merger. Gothic shareholders (other than Chesapeake) received 0.1908 of a share of Chesapeake common stock for each share of Gothic common stock. In addition, outstanding warrants and options to purchase Gothic common stock were converted to the right to purchase Chesapeake common stock based on the 0.1908 exchange ratio. Gothic preferred stock, all of which is owned by Chesapeake, remains outstanding. As part of the merger, the terms of the Gothic preferred stock were amended to eliminate the right to convert the Gothic preferred stock to Gothic common stock. Prior to the merger, Chesapeake purchased substantially all of Gothic's 14.125% senior secured discount notes (total accreted principal amount of $104 million) and $31.6 million of $235 million principal amount of 11.125% senior secured notes issued by Gothic's subsidiary. As part of the merger the $31.6 million principal amount of 11.125% senior secured notes were retired. The outstanding notes continue to be the obligations of Gothic and its subsidiary. The issuance of Chesapeake common stock under the merger agreement was registered under the Securities Act of 1933 pursuant to Chesapeake's registration statement on Form S-4 (No. 333-47330). The proxy statement/prospectus included in the registration statement contains additional information about the transaction. The Gothic shareholders approved the merger at a special meeting of shareholders on December 12, 2000. ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS (a) Financial statements of businesses acquired: The financial statements of Gothic Energy Corporation ("Gothic") as of and for the nine months ended September 30, 2000, as filed on Form 10-Q, and for the year ended December 31, 1999, as filed on Form 10-K, are incorporated herein by reference. (b) Pro forma financial information: The unaudited pro forma financial information required pursuant to Article 11 of Regulation S-X is filed herewith. 2

4 PRO FORMA COMBINED FINANCIAL DATA The following unaudited pro forma combined financial statements are derived from the historical financial statements of Chesapeake Energy Corporation and Gothic Energy Corporation. The pro forma combined statements of operations for the nine months ended September 30, 2000 and for the year ended December 31, 1999 reflect the Gothic acquisition, accounted for as a purchase, as if the acquisition occurred on January 1, 1999. The pro forma combined balance sheet at September 30, 2000 reflects the consummation of the Gothic acquisition as if it occurred on September 30, 2000. The unaudited pro forma combined financial data should be read in conjunction with the notes thereto and the historical financial statements of Chesapeake and Gothic, including the notes thereto. 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. In addition, future results may vary significantly from the results reflected in such statements due to general economic conditions, oil and gas commodity prices, Chesapeake's ability to successfully integrate the operations of Gothic with its current business and several other factors, many of which are beyond Chesapeake's control. The Gothic acquisition will be accounted for using the purchase method. The purchase cost will be allocated to the Gothic assets and liabilities based on their respective fair values. The final allocation of the actual purchase price is subject to the final valuation of the acquired assets, but that allocation is not expected to differ materially from the preliminary allocation presented in these pro forma combined financial statements. 4

8 NOTES TO UNAUDITED PRO FORMA COMBINED FINANCIAL DATA (a) The purchase price reflects the issuance of: o 4.0 million shares of Chesapeake common stock in exchange for all outstanding shares of Gothic common stock (other than shares of Gothic common stock held by Chesapeake) and o Chesapeake warrants and options to purchase 2.9 million shares of Chesapeake common stock in exchange for all of the outstanding warrants and options to purchase shares of Gothic common stock based on the exchange ratio of 0.1908 of a share of Chesapeake common stock for each share of Gothic common stock. The Chesapeake common stock issued as merger consideration is valued based on a price per share of $7.00, which was the closing price of Chesapeake common stock on the day before the merger was announced. The purchase price also reflects: (i) acquisition costs of approximately $10.0 million (including $2.1 million for estimated termination costs of Gothic employees); (ii) Chesapeake's investment in Gothic preferred and common stock, which has a carrying value of $10 million; and (iii) Chesapeake's investment in Gothic senior secured discount notes and senior secured notes. Chesapeake estimates that the fair value of the Gothic senior secured notes equals 106% of their face value. The purchase price also gives effect to the estimated fair value of out-of-the-money Gothic warrants to be assumed by Chesapeake. Below is a summary of the purchase price allocation to the estimated fair value of the assets acquired and liabilities assumed ($ in 000's): Issuance of common stock........................................ $ 28,000 Investment in Gothic senior secured discount notes.............. 80,761 Investment in Gothic senior secured notes (see Note (b))........ 34,760 Investment in Gothic preferred and common stock................. 10,000 Fair value of Gothic warrants................................... 1,500 Other acquisition costs......................................... 10,000 --------- Purchase price........................................ $ 165,021 ========= GOTHIC ESTIMATED PRO FORMA BOOK VALUE FAIR VALUE ADJUSTMENT ---------- ---------- ---------- Current assets............................................... $ 30,270 $ 30,270 $ -- Property and equipment-- proved properties................... 273,682 368,837 95,155 Property and equipment-- unproved properties................. 6,233 10,000 3,767 Accumulated DD&A.............................................

The $34.8 million investment in senior secured notes includes a total premium of $3.1 million. (c) To record DD&A expense of oil and gas properties using a rate of $0.82 per mcfe. This combined rate reflects the impact of the allocation of purchase price to Gothic's proved oil and gas properties. (d) To record the tax effects of the pro forma adjustments at a statutory rate of 40%.

(983) (983) --------------- --------------- Diluted shares outstanding-- as adjusted ......... 150,445 118,608 =============== =============== (f) To eliminate dividends on Gothic's preferred stock held by Chesapeake. (g) To eliminate interest expense and amortization costs related to the senior discount notes and senior secured notes acquired by Chesapeake. (h) To reclassify overhead reimbursements recognized by Gothic as operator of certain oil and gas properties and reported as well operations revenue. These reimbursements have been reclassified as a reduction to general and administrative expenses to conform with Chesapeake's presentation of similar reimbursements. (i) To record the initial financing fees (net of income tax) incurred by Chesapeake to establish a standby credit facility to fund purchases of Gothic senior secured notes tendered after the merger pursuant to a change-of-control offer to purchase the notes at 101% principal amount. Chesapeake believes the standby credit facility will not be utilized, and therefore the associated fees will be expensed when the holders' change-of-control put options expire. Chesapeake incurred $688 thousand in such costs prior to September 30, 2000 and $2.6 million subsequent thereto. If, however, the standby credit facility is utilized, Chesapeake will incur an additional $2.75 million in financing costs and the total financing costs of $6 million will be deferred and amortized over the twenty-six month term of the facility. Assuming the standby credit facility is utilized to (a) purchase the outstanding Gothic senior secured notes and (b) replace Chesapeake's current line of credit, the pro forma results of operations would reflect an increase in interest expense of approximately $1.7 million and $2.7 million for the nine months ended September 30, 2000 and the year ended December 31, 1999, respectively. (j) To record the effects of certain make-whole provisions associated with Chesapeake's investment in Gothic's 14.125% senior discount notes and 11.125% senior secured notes. At the time of the acquisition of the notes, Chesapeake issued 13.6 million shares of Chesapeake common stock and paid $23.3 million in cash to acquire the notes. Subsequent to September 30, 2000, Chesapeake received $974 thousand in cash and 982,588 shares of Chesapeake common stock based upon the make-whole provisions contained in the purchase agreements. (k) To adjust the purchase price allocation and accrued merger-related costs for amounts incurred through September 30, 2000. (l) To record payments that will be made to Gothic's CEO and CFO following the merger pursuant to two-year non-compete agreements. (m) Estimated total pro forma proved reserves at September 30, 2000 were as follows (in MMcfe): Chesapeake .................................................... 1,322,192 Gothic ........................................................ 310,032 --------- As adjusted .............................................. 1,632,224 ========= 9
