      On June 23, 1998, the Company announced an accounting change for
its oil and gas exploration and production subsidiary which required the
Company to record a one-time, non-cash reduction of shareholders' equity
of about $176 million after tax.  As a result of the accounting change,
the Company's financial statements for prior periods have been restated. 
Shareholder equity as restated was $1.787 billion at year-end 1997.  Refer
to Forms 8-K dated June 23 and July 30, 1998 for further discussion of
this accounting change and copies of these restated financial statements.

      On August 3, 1998, the Company announced the execution of a merger
agreement with Continental Natural Gas, Inc. ("CNGL"), a $185 million
(assets) energy company engaged in gathering, processing, purchasing and
marketing natural gas and natural gas liquids in Oklahoma and Texas. 
Approximately $65 million of CMS Energy Common Stock will be issued to
acquire 100% of CNGL's common stock and approximately $90 million of CNGL
debt will be assumed in the transaction, which is intended to be accounted
for as a pooling of interests.  The merger agreement is subject to
ratification by the holders of a majority of CNGL's common stock.  The
transaction is expected to close early in the fourth quarter of 1998. 
Other than compliance with the Hart-Scott-Rodino Act, the transaction does
not require any governmental approvals.
