EXHIBIT 99.1 PRESS RELEASE FOR IMMEDIATE RELEASE CONTACTS: COLUMBIA ENERGY GROUP NATIONAL PROPANE R. A. RANKIN, JR. (NEWS MEDIA) R. BROOKS SHERMAN (703) 561-6044 (319) 365-1550 THOMAS L. HUGHES (FINANCIAL COMMUNITY) (703) 561-6001 COLUMBIA PROPANE TO ACQUIRE NATIONAL PROPANE FOR $12.00 IN CASH PER COMMON UNIT Richmond, VA and Cedar Rapids, IA, April 5, 1999 -- Columbia Propane Corporation (Columbia Propane), a subsidiary of Columbia Energy Group (NYSE: CG), and National Propane Partners, L.P. (NYSE: NPL) announced today that they have signed a definitive purchase agreement whereby Columbia Propane will commence a tender offer to acquire all of the approximately 6.7 million outstanding common units of National Propane for $12.00 in cash per common unit. Subject to the terms and conditions of the agreement, Columbia Propane would also acquire the general partner interests and subordinated unit interests of National Propane from subsidiaries of Triarc Companies, Inc. (NYSE: TRY). Approximately $141 million of National Propane's outstanding indebtedness is expected to be refinanced by Columbia Propane in connection with the transaction. The proposed acquisition of National Propane would add more than 210,000 retail and wholesale customers in 24 states, extending Columbia Propane's presence from the Mid-Atlantic and Northeast to the Southeast, Midwest and Western regions of the United States. The combination would also result in Columbia Propane having more than 300,000 customers with operations in 35 states and the District of Columbia. "With today's announcement, Columbia Propane is aggressively executing part of the Group's nonregulated growth strategy," said Oliver G. Richard III, Chairman, President and CEO, of Columbia Energy Group. "The National Propane acquisition gives Columbia Propane the opportunity to triple the size of its customer base, and rank among America's leading propane companies." Ronald R. Rominiecki, President and Chief Operating Officer of National Propane, said: "The Columbia Propane transaction will significantly improve National Propane's growth prospects. At a significant premium to today's closing market price, the Columbia Propane acquisition is a very attractive transaction for our common unitholders which our Board fully supports." The Board of Directors of National Propane's managing general partner, acting on the recommendation of its Special Committee, has unanimously approved the Columbia Propane transaction and unanimously recommended that unitholders tender their common units pursuant to the offer. The Special Committee received an opinion of Lehman Brothers that, from a financial point of view, the consideration to be received by the common unitholders in the proposed transaction is fair to the common unitholders. The tender offer is the first step of a two-step cash transaction. In the second step, subject to the terms and conditions of the purchase agreement among the parties, Columbia Propane would indirectly acquire the general partnership interests and subordinated unit interests of National Propane from subsidiaries of Triarc and National Propane would merge into Columbia Propane, L.P. As part of the second step, any remaining common unitholders of National Propane would receive, in cash, the same per unit price as that paid to unitholders who tender their shares pursuant to the tender offer. Triarc would receive approximately $17.9 million for its acquired interests in National Propane - $2.1 million in cash and $15.8 million payable in the form of the forgiveness of indebtedness owed by Triarc to National Propane. Simultaneously, and as a condition of the closing, Triarc will prepay approximately $14.9 million of such indebtedness. The managing general partner of National Propane has also agreed to, among other things, execute a consent, as holder of all the subordinated units, to approve the merger and other transactions contemplated by the agreement. Columbia Propane, through its direct and indirect subsidiaries CP Holdings, Inc. and Columbia Propane, L.P., intends to commence its cash tender offer for all of the outstanding common units of National Propane at a price of $12.00 per unit, net to the seller in cash, beginning April 9, 1999. The offer for the common units will be subject to certain conditions, including there being validly tendered by the expiration date, and not withdrawn, at least a majority of the outstanding common units on a fully diluted basis. The offer will be made only upon and subject to the terms and conditions of the Offer to Purchase and the related Letter of Transmittal. National Propane Partners, L.P. has operations concentrated in the Midwest, Northeast, Southeast and Western regions of the United States and serves over 210,000 active customers through its 155 full service centers.
