Support for Pepco Holdings-Exelon Merger Grows as More D.C. Community, Business and Faith Leaders Speak Out

More than 600 community members have signed letters in support of
merger this week

WASHINGTON & CHICAGO–(BUSINESS WIRE)–More District of Columbia community, business, labor, nonprofit and
faith leaders are voicing support for the Pepco Holdings-Exelon merger,
which will bring increased reliability, sustainability and economic
benefits to the region. In addition, in the past week, more than 600
members of the community have signed letters voicing support for the
merger.

Among those speaking out in favor of the merger are community and
economic development leaders, and senior officials of several businesses
and labor organizations.

“A more reliable electric grid and a strong commitment to affordable
rates will help the economy, and that helps workers,” said Andre Lee,
political chairman of the American Federation of State, County and
Municipal Employees. “I’m also encouraged to see Pepco Holdings and
Exelon make workforce development and investment in the District economy
a key feature of their merger.”

Lee and other new supporters join representatives of more than 80
District business, community and faith organizations that already voiced
support for the transaction in proceedings before the Public Service
Commission of the District of Columbia (PSC).

“The merger presents a unique opportunity to improve quality of life for
residents in the District,” said Rayseen Woodland, a community leader
and current ANC commissioner. “Pepco Holdings and Exelon have made a
long-term commitment to enhance customer service and support the
organizations and institutions that make our neighborhoods stronger.”

Pepco Holdings and Exelon have committed to a more than $78 million
package of benefits for the District of Columbia and Pepco customers in
the companies’ proposed merger.

“These commitments will support District residents who struggle to pay
their bills,” said Marshall Phillips, minister at the Greater Mount
Calvary Holy Church. “None of that would be possible absent the merger,
and that’s why it is critical that we not miss this opportunity.”

Anwar Saleem, executive director of H Street Main Street, said the
companies’ commitment to provide $19 million to District nonprofits over
10 years demonstrates their long-term commitment to strengthening
communities and the local economy.

“The merger ensures that Pepco remains a strong, invested community
partner for years to come,” he said.

Charles Weaver, president of the Jetu Tenants Association, said he
supports the merger because it will increase access to renewable energy
and commit the companies to reducing the length and duration of power
outages.

“We need a modern, more sustainable electricity grid that also holds the
line on rates,” he said. “This merger delivers on that promise.”

merger may not be satisfied; (3) problems may arise in successfully
integrating the businesses of the companies, which may result in the
combined company not operating as effectively and efficiently as expected;
(4) the combined company may be unable to achieve cost-cutting
synergies or it may take longer than expected to achieve those
synergies; (5) the merger may involve unexpected costs, unexpected
liabilities or unexpected delays, or the effects of purchase accounting
may be different from the companies’ expectations; (6) the credit
ratings of the combined company or its subsidiaries may be different
from what the companies expect; (7) the businesses of the
companies may suffer as a result of uncertainty surrounding the merger;
