Other Events. On September 13, 1999, KeySpan Corporation d/b/a KeySpan Energy ("the Company") issued a press release concerning, its intention to begin a process to review strategic alternatives for the Houston Exploration Company, in which the Company has a 64% share ownership. The Company's press release is attached hereto as Exhibit 99 and is incorporated herein by reference. In addition, the Company currently believes that its earnings for the year ending December 31, 1999, will exceed most securities analysts' estimates. The full range of analyst earnings projections is $1.40 - $1.60 per common share. Based on current projections, it appears as if earnings for this period will be at the upper end of this range primarily as a result of reduced costs and the benefits derived from the acquisition of the Ravenswood generating facility in June 1999. Certain statements contained here in or in the exhibits attached hereto concerning expectations, beliefs, plans, objectives, goals, strategies, future events or performance and underlying assumptions and other statements which are other than statements of historical facts, are "forward-looking statements" within the meaning of Section 21E of the Securities Exchange Act of 1934, as amended. Such forward-looking statements reflect numerous assumptions and involve a number of risks and uncertainties and actual results may differ materially from those discussed in such statements. Among the factors that could cause actual results to differ materially are: available sources and cost of fuel; federal and state regulatory initiatives that increase competition, threaten cost and investment recovery, and impact rate structures; the ability of the Company to successfully reduce its cost structure; the successful integration of the Company's subsidiaries; the degree to which the Company develops unregulated business ventures; the ability of the Company to identify and make complementary acquisitions, as well as the successful integration of such acquisitions; inflationary trends and interest rates; the ability of the Company and its significant vendors to modify their computer software, hardware and databases to accommodate the year 2000; and other risks detailed from time to time in other reports and other documents filed by the Company with the Securities and Exchange Commission. For any of these statements, the Company claims the protection of the safe harbor for forward-looking information contained in the Private Securities Litigation Reform Act of 1995, as amended.

KEYSPAN CORPORATION Dated: September 16, 1999 By: /s/ Robert R. Wieczorek Title: Vice President, Treasurer and Secretary INDEX TO EXHIBITS Exhibit No. Exhibit Page 99 Press Release, dated September 13, 1999 5 Exhibit 99 HOUSTON EXPLORATION AND MAJORITY SHAREHOLDER, KEYSPAN ENERGY, ANNOUNCE INTENTION TO EXPLORE STRATEGIC ALTERNATIVES FOR HOUSTON EXPLORATION HOUSTON, Brooklyn, and Hicksville, N.Y.--(BUSINESS WIRE)--Sept. 13, 1999-- The Houston Exploration Company (NYSE:THX - news) and its majority shareholder, KeySpan Energy Corporation (NYSE:KSE - news), jointly announced today their intention to begin a process to review strategic alternatives for Houston Exploration. The process will include an assessment of the role of Houston Exploration within KeySpan's future strategic plan, and will consider a full range of strategic transactions which could include the sale of all or a portion of Houston Exploration. J.P. Morgan Securities Inc. has been retained by Keyspan as financial advisor to assist in this strategic review. "The management team at Houston Exploration has developed an outstanding track record and has built a portfolio of exploration opportunities whose value is likely to be enhanced substantially by a company focused solely on oil and gas exploration and production," said Robert B. Catell, chairman and chief executive officer of KeySpan Energy. "In today's competitive market, KeySpan's strategy is centered on growing its core downstream businesses, including gas and electric distribution, electric generation, and energy services in the Northeast region. We believe our assessment of options at this time will result in the maximum value for the shareholders of both companies," Mr. Catell said. James G. Floyd, president and chief executive officer of Houston Exploration said, "With a strong commodity-pricing and lower service-cost environment, Houston Exploration will continue to develop its substantial inventory of high-quality prospects for the benefit of all its shareholders. All operating activities will continue as planned while the various options are being evaluated." The Houston Exploration Company is a Houston-based independent natural gas and oil company engaged in the exploration, development and acquisition of domestic natural gas and oil properties. The company's offshore properties are located in the shallow water Gulf of Mexico and its onshore properties are located in South Texas, the Arkoma Basin, South Louisiana, East Texas and West Virginia. KeySpan Energy is a holding company including two utilities that distribute natural gas under the Brooklyn Union name to 1.6 million customers in New York City and on Long Island, making it the fourth largest gas-distribution company in the United States. Other KeySpan companies market a portfolio of energy-related services in the Northeast, own or operate electric- generation plants in New York City and on Long Island, and provide operating and customer services to one-million electric customers of the Long Island Power Authority. KeySpan's unregulated energy activities focus on three principal lines of business: gas exploration and development, primarily through The Houston Exploration Company; domestic pipelines and storage; and international activities, including gas-processing in Canada, and gas pipelines and local-distribution in Northern Ireland.
