CHARLOTTE, N.C. and CINCINNATI, OHIO - Cinergy (CIN) and Duke Energy (DUK) today
announced they have entered into a definitive merger agreement to create an
energy company with approximately $36 billion in market capitalization and 5.4
million retail customers.

The merger, which was unanimously approved by both companies' boards of
directors, will create a combined energy company with assets totaling more than
$70 billion.

The combined company, to be named Duke Energy Corporation, will have
approximately $27 billion in annual revenues and $1.9 billion in annual net
income (combined figures as of Dec. 31, 2004). It will own and/or operate
approximately 54,000 megawatts of electric generation domestically and
internationally - relying on a diverse fuel mix of nuclear, coal, natural gas
and hydroelectric power to meet customers' needs. Duke Energy also operates more
than 17,500 miles of natural gas transmission pipeline with 250 billion cubic
feet of natural gas storage capacity and, through its joint venture with
ConocoPhillips, is the largest producer of natural gas liquids (NGLs) in North
America. The combined company will have operations in two-thirds of the United
States, as well as Canada and several other international locations - primarily
in Latin America.

By combining resources and best practices, the merger will enhance operations
and create efficiencies at all levels of the new company, including generation,
transmission and distribution as well as power and gas marketing.

Under the merger agreement, each common share of Cinergy will be converted into
1.56 shares of Duke Energy upon closing of the merger. Based on the closing
prices on May 6, Cinergy investors will receive a premium of 13.4 percent.
Following the merger, Cinergy shareholders will own approximately 24 percent, or
about 310 million shares, of Duke Energy pro-forma shares outstanding, and Duke
Energy shareholders will own approximately 76 percent of the total 1.3 billion
shares. The transaction will be accretive to Duke Energy's earnings in the first
full year of operation.

Upon completion of the merger, Paul M. Anderson, currently chairman and chief
executive officer of Duke Energy, will become chairman of the board of the
combined company. James E. Rogers, currently chairman, president and chief
executive officer of Cinergy, will become president and chief executive officer.
The new board will be comprised initially of 10 members named by Duke Energy and
five members named by Cinergy.

"The combination of Duke Energy and Cinergy will create a rock-solid portfolio
of electric and gas businesses, increasing value for our shareholders





immediately and in the longer term," said Anderson. "This union is a great
strategic fit and leaves us well positioned for continued consolidation in the
energy sector as both the electric and gas businesses will have the scale to
stand alone. Importantly, it also provides an immediate and significant
improvement for our merchant operations and enhances their future prospects.

"Just as significant as the strong strategic fit of our companies is the
cultural fit. Duke Energy and Cinergy share compatible values, operating
philosophies and views of the future," Anderson said.

"The increased scope and scale will make the combined company a major industry
leader with a strong balance sheet, complementary assets and a low-cost
generation portfolio," said Rogers. "Both companies are known for operational
excellence as well as strong customer service and reliability.

"We are creating a top-tier energy company that will assume a key leadership
role in the future of our industry while delivering benefits to all of our
stakeholders. Moreover, this combination creates a stronger platform from which
to continue our leadership in finding practical solutions to the environmental
challenges facing our industry and country."

Benefits of the Merger
The merger will deliver significant value to customers and shareholders of both
companies:

Increased Scale and Scope of Regulated Businesses: The combined company will
create a stronger portfolio of utility businesses with 3.7 million retail
electric customers and 1.7 million retail gas customers in Ohio, Kentucky,
Indiana, North Carolina, South Carolina and Ontario, Canada. The retail electric
businesses will have more than 25,000 megawatts of generation and broad
operational and regulatory experience. Coupled with the company's pipeline
operations, the regulated businesses will contribute a substantial percentage of
stable earnings and create the financial strength and scale to participate in
the continuing consolidation of the utility sector.

Stronger Merchant Power Platform: With a fleet of more than 16,000 megawatts of
unregulated generation, the combined merchant power operation will benefit from
increased fuel and market diversity. Consolidation of the trading and marketing
units and midwestern merchant generating fleets will enhance scale and
efficiencies -- reducing the cost structure of merchant operations by
approximately $95 million during year one and $125 million per year
subsequently. Significantly, Duke Energy's gas-fired generation in the Midwest
complements Cinergy's coal-fired generation in that region. The merchant
operations, with a competitive market presence in North America and South
America, will be well positioned to participate in the continuing consolidation
of the wholesale power sector.

Increased Duke Energy Dividend Creates Immediate Shareholder Value: In
conjunction with today's merger announcement, Duke Energy's board of directors
said it intends to increase Duke Energy's dividend by 12.7 percent, or 14 cents
a year, for an annual dividend of $1.24. The dividend increase, which will be
voted on during the board's June meeting, would be effective with the September
2005 disbursement. As a result of the merger transaction and the Duke Energy
dividend increase, Cinergy shareholders will be kept whole at closing with
respect to their current dividend.

Continued Financial Strength: Increased scale and scope will also strengthen the
balance sheet of the combined company, improving financial flexibility and
positioning it well for the future. The combined company will have electric and
gas businesses with stand-alone scale. Based on implied market capitalization,
the electric business would be one of the top five in the United States; the gas
business would be the largest in North America.

Significant Synergies: The merger offers both strategic and financial advantages
in serving the energy marketplace. Not including implementation costs, the
combination will generate approximately $400 million in annual gross synergies
- -- when fully realized in year three -- from across corporate activities,
regulated utilities and non-regulated marketing, trading and generation
businesses. These cost savings will result from elimination of duplicate
spending and overlapping functions, improved sourcing strategies, avoidance of
planned expenditures and the consolidation of non-regulated business unit
operations. The combined companies currently employ approximately 29,350 and
expect a reduction of approximately 1,500, primarily through attrition, early
retirements and other severance programs. The companies anticipate that upon
review with state commissions, regulated savings will be shared between
customers and shareholders over time in an equitable manner.

Steadfast Community Involvement: Duke Energy and Cinergy have long been
committed to the communities in which they operate. That demonstrated commitment
will continue through local presence, economic development efforts and corporate
contributions.





Structure and Organization
Following the merger, the combined company will be a registered holding company
with corporate headquarters in Charlotte, N.C. Local headquarters of the
operating utilities will remain unchanged by the merger: Cincinnati Gas &
Electric Company and Union Light, Heat & Power will remain in Cincinnati; PSI
Energy will remain in Plainfield, Indiana; and Duke Power will continue to be
headquartered in Charlotte. Duke Energy Gas Transmission (DEGT) and certain
commercial operations will remain in Houston. Duke Energy Field Services (DEFS)
will remain headquartered in Denver and Crescent Resources will continue to be
located in Charlotte.

At the completion of the merger, Rogers will have responsibility for all Duke
Energy's business units, corporate functions and support services with the
exception of the company's gas businesses: DEGT and DEFS. At closing, Fred
Fowler, currently president of Duke Energy, will become president and chief
executive officer of these gas operations, reporting to Rogers on operations and
to Anderson on strategy, pending completion of a strategic review of the
portfolio.


Approvals and Timing
The merger is conditioned upon approval by the shareholders of both companies,
as well as a number of regulatory approvals or reviews by federal and state
energy authorities, including the North Carolina Utilities Commission, the
Public Service Commission of South Carolina, the Public Utilities Commission of
Ohio, the Kentucky Public Service Commission, the Indiana Utility Regulatory
Commission, the Federal Energy Regulatory Commission (FERC), the Nuclear
Regulatory Commission (for assurance of continuing financial qualifications and
operational standards), the Securities and Exchange Commission (SEC) and the
Department of Justice.

The new company intends to register as a holding company with SEC under the
Public Utility Holding Company Act. The companies anticipate making required
regulatory filings by July 2005, with necessary approvals obtained in about 12
months. The companies will work to secure necessary government approvals
consistent with FERC's Merger Policy Statement and the Hart-Scott-Rodino
Antitrust Improvements Act.
