1 SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 FORM 8-K FOR ILLINOVA CORPORATION an Illinois corporation IRS Employer Identification No. 37-1319890 SEC File Number 1-11327 500 SOUTH 27TH STREET DECATUR, ILLINOIS 62521 (217) 424-6600 June 14, 1999 2 ITEM 5. OTHER EVENTS. On June 14, 1999, Illinova Corporation, an Illinois corporation ("Illinova"), and Dynegy Inc., a Delaware corporation ("Dynegy"), agreed to combine in a transaction in which each of Illinova and Dynegy will become wholly owned subsidiaries of Energy Convergence Holding Company, a newly formed Illinois corporation ("Newco"). Energy Convergence Acquisition Corporation, an Illinois corporation and a wholly owned subsidiary of Newco, will be merged with and into Illinova, and Dynegy Acquisition Corporation, a Delaware corporation and a wholly owned subsidiary of Newco, will be merged with and into Dynegy. The terms of the Merger are set forth in an Agreement and Plan of Merger (the "Merger Agreement") dated as of June 14, 1999 among Newco, Illinova, Energy Convergence Acquisition Corporation, Dynegy and Dynegy Acquisition Corporation. In the combination, each share of Illinova common stock, no par value per share, will be converted into one share of Newco common stock, no par value per share (the "Newco Common Stock"), and each share of Dynegy common stock, par value $.01 per share, and Dynegy Series A Participating Preferred Stock, par value $.01 per share (collectively, the "Dynegy Stock"), will be converted into the right to receive either $16.50 in cash or 0.69 of a share of Newco Common Stock pursuant to an election process and the pro ration of approximately $1.1 billion among Dynegy shareholders electing to receive cash. The cash portion of the consideration received by Dynegy's shareholders will be approximately 40% of the total consideration. The combination is intended to constitute a tax-free contribution under the Internal Revenue Code of 1986, as amended. Dynegy has three large shareholders, Nova Gas Services (U.S.) Inc., an affiliate of BG plc and Chevron U.S.A. Inc., which collectively own approximately 76% of Dynegy's outstanding equity securities. Of these shareholders, Nova and BG will be electing to receive the maximum amount of cash possible and Chevron will be electing to receive the maximum amount of Newco Common Stock possible. Because of the size of Nova's and BG's ownership positions, some pro ration of the cash portion of the consideration will occur. To the extent that Nova and BG would receive Newco Common Stock in the combination they instead will receive Newco Series A Convertible Preferred Stock. Newco's Series A Convertible Preferred Stock is convertible into Newco Common Stock at the election of the holder and is subject to redemption at the election of Newco after three years. Holders generally are entitled to vote together with holders of Newco Common Stock in proportion to the economic interest of such shares. Similarly, to the extent that Chevron would receive Newco Common Stock, it will receive Newco Class B Common Stock. In general, the terms of the Newco Class B Common Stock provide Chevron board representation, certain rights and limitations with respect to purchases and sales of Newco securities and certain "blocking rights" with respect to large transactions by Newco. In addition, the terms require that Chevron, should its ownership interest ever exceed 40% of Newco's equity securities, offer to purchase the remaining equity securities of Newco in accordance with established procedures. 3 Consummation of the combination is subject to various conditions, including: (i) receipt of necessary approvals by the stockholders of each of Illinova and Dynegy; (ii) the expiration or termination of applicable waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended; (iii) the exemption of the acquisition by Chevron of Newco's Class B Common Stock under the Public Utility Holding Company Act and the receipt of necessary Federal Energy Regulatory Commission and Illinois Commerce Commission approvals; (iv) the consummation by Illinova of its previously announced sale of its Clinton nuclear facility; (v) registration of the shares of Newco Common Stock to be issued in the merger under the Securities Act of 1933, as amended; and (vi) satisfaction of certain other conditions. The foregoing summary of the combination is qualified in its entirety by reference to the texts of the Merger Agreement, Shareholder Agreement and other documents that are filed as exhibits hereto.
