 NUI CORP. ANNOUNCES RESOLUTION OF INVESTIGATION BY
NEW JERSEY STATE ATTORNEY GENERAL'S OFFICE

 Bedminster, NJ - June 30, 2004 - NUI Corporation (NYSE:NUI) today announced that its wholesale energy trading subsidiary, NUI Energy Brokers, Inc. (NUIEB), has entered into a plea agreement with the New Jersey Attorney General's Office relating to certain transactions at NUIEB.  Pursuant to the plea agreement, NUIEB pleaded guilty today to Misconduct by a Corporate Official.  NUIEB expects to pay a $500,000 fine in connection with the plea.  NUI has entered into a separate agreement with the New Jersey State Attorney General's Office pursuant to which NUI has agreed to develop, fund and operate certain community service programs.

This concludes the investigation by the Attorney General's Office of NUI Corporation and its subsidiaries.  The New Jersey Board of Public Utilities (NJBPU) concluded a similar review of NUI and NUIEB in April, with the conclusion of a focused audit of the company that ended with the NJBPU ordering a $28 million refund to customers and a $2 million fine.

Craig G. Matthews, NUI President and Chief Executive Officer, stated,  "When I joined the company, the NUI Board made it clear that we were to conclude the various investigations into the company and proceed with the sale process.  These agreements with the New Jersey State Attorney General and the settlement with the New Jersey Board of Public Utilities brings closure to the investigations by these parties of the company's energy trading business.  The completion of these investigations should help facilitate the sale of the company."

NUI expects to sign a definitive agreement with a purchaser of the company in the third quarter of calendar 2004.

NUI Corporation, based in Bedminster, NJ, is an energy company that operates natural gas utilities and businesses involved in natural gas storage and pipeline activities.  NUI Utilities' divisions include Elizabethtown Gas in New Jersey, City Gas Company of Florida and Elkton Gas in Maryland.
