October 1, 1997 Upon Receipt Clifford J. Hebert, Jr. (617) 357-9590 Eastern Utilities/Duke Partnership Terminated BOSTON, Oct. 1 - Eastern Utilities Associates (NYSE: EUA), and an affiliate of Duke Energy Corp. (NYSE: DUK), today announced they are terminating their New England power marketing joint venture. Financial terms of the agreement were not disclosed, but EUA Treasurer Clifford J. Hebert, Jr., said EUA anticipates a one-time positive impact on its third- quarter financial results from the termination. The amount of the gain has not yet been finally determined. EUA and a Duke affiliate had agreed in December 1995 to form the joint venture to engage in power marketing and other energy-related services throughout New England. "Today's decision enables EUA and Duke to pursue market opportunities in New England on an individual basis," Hebert said.
