1 EXHIBIT 99.1 DLB OIL & GAS, INC. 1601 N.W. Expressway, Suite 700 Oklahoma City, OK 73118-1401 Phone: 405-848-8808 Fax: 405-848-9449 NEWS RELEASE For Further Information FOR IMMEDIATE RELEASE Contact: Fred Standefer Vice President Corporation Development (405) 848-8808 DLB TO MERGE MID-CONTINENT/BARBADOS ASSETS INTO CHESAPEAKE ENERGY CORPORATION, AND SPIN-OFF BAYARD AND WRT OKLAHOMA CITY, OKLAHOMA - October 22, 1997 - DLB Oil & Gas, Inc. (NASDAQ-DLBI) today announced that it has entered into a definitive merger agreement with Chesapeake Energy Corporation pursuant to which DLB shareholders will realize the value of their DLB shares in the form of three separate securities. Consideration will consist of $65 million of Chesapeake common stock and the assumption of approximately $85 million in debt and other liabilities for DLB's Mid-Continent and Barbados oil and gas assets. As of June 30, 1997, proved reserves attributable to these properties were estimated by the Company to be approximately 27 million barrels of oil equivalent. In addition, as part of the transaction, DLB shareholders will receive their proportionate share of the common stock of Bayard Drilling Technologies, Inc. (Bayard) and WRT Energy, Inc. (WRT) owned by DLB. DLB currently owns 2,955,000 shares of Bayard and 10,354,198 shares of WRT, all of which will be distributed to DLB shareholders. Charles Davidson, DLB's Chairman, said, "This merger will allow DLB shareholders to enjoy the benefits of direct ownership of the three distinct assets currently in our portfolio. First, each of us as shareholders will own equity in Bayard Drilling, which is one of the largest land contract drilling companies in the United States. Second, we will achieve significant operational synergies by combining our Mid-Continent assets and our team with Chesapeake. Third, by virtue of our WRT position, we will also own interests in a focused South Louisiana exploration and production company with excellent core assets in one of the most exciting areas in the country. We believe this realignment of our three core businesses will ultimately maximize the value inherent in each unique segment." 2 Mark Liddell, DLB's President, stated "Strategically, we believe this transaction creates the best way to participate in the rapid consolidation we see occurring in both oil field services and exploration and production. Our fellow shareholders will experience higher liquidity, diversification, and increased exposure to the positive effects of the consolidation process." Under the terms of the merger, a subsidiary of Chesapeake will merge with and into DLB. In the merger, shares of DLB common stock will be converted into the right to receive: (1) a fractional interest in a share of Chesapeake common stock equal to $65 million divided by the average of the closing prices of Chesapeake stock for each of the first 20 consecutive trading days in the period commencing 25 trading days prior to the date of DLB's special stockholders meeting with respect to the merger, divided by the number of shares outstanding on the closing date, (2) a number of shares of Bayard common stock equal to 2,955,000 divided by the number of DLB shares outstanding on the closing date, and (3) a number of shares of WRT common stock equal to 10,354,198 divided by the number of DLB shares outstanding on the closing date. In the event that the average closing price for Chesapeake common stock used in this calculation is less than $7.50 per share, each of DLB and Chesapeake shall have the right, but not the obligation, to terminate the merger agreement. Chesapeake will have the option to pay $65 million in cash rather than in shares of Chesapeake common stock. The merger is subject to approval of the holders of at least a majority of the outstanding shares of DLB common stock as of the record date for the DLB special shareholders meeting. The company anticipates a mid-January date for the special meeting of shareholders. DLB currently has 12,975,000 shares outstanding. Option acceleration under existing incentive plans may affect the shares outstanding at closing. Charles Davidson, Mark Liddell and Mike Liddell, who collectively own over 75% of DLB's outstanding common stock, have entered into an agreement with Chesapeake pursuant to which, among other things, they have agreed to vote in favor of the merger at the DLB special meeting. The distributions of the WRT and Bayard shares will be subject to the effectiveness of registration statements for such shares under the Securities Act of 1933. In addition, the shares of Bayard, assuming a successful initial public offering, will not be distributed until the expiration of 180 days from the date of the pricing of Bayard's IPO. Pending distribution of the WRT and Bayard shares, the shares will be held in escrow by the exchange agent for the merger. Lehman Brothers acted as DLB's financial advisor in connection with the merger and DLB's review of strategic alternatives.
