ACE USA Makes Donation to American Forests to Support National Tree-Planting Projects

5,000 Trees to Be Planted as Part of Forestry Restoration Program
PHILADELPHIA--(Business Wire)--
ACE USA, the U.S.-based retail operating division of the ACE Group
of Companies, today announced that its environmental liability
division, ACE Environmental Risk, has made a donation to American
Forests as part of its Global ReLeaf campaign, to fund the planting of
5,000 trees in five locations across the United States. ACE
Environmental Risk is making this donation in appreciation for its
clients' support in 2007.

American Forests, one of the first organizations to address the
issue of global warming, helps people understand the many values of
trees and the need to restore forest ecosystems in urban and rural
areas through community-based initiatives. The organization introduced
Global ReLeaf2 in 2007 to help cool the globe through the planting of
trees. The goal of this campaign is to plant 100 million trees by the
year 2020.

"ACE is committed to doing its part to protect the environment by
supporting a variety of initiatives, including serving as a partner in
the United States Environmental Protection Agency-sponsored Climate
Leaders program and launching ACE Green, the Company's global employee
environmental program," said William Hazelton, Senior Vice President,
ACE Environmental Risk. "As millions of people across the world come
together to prepare for Earth Day celebrations later this month, we're
delighted to take action by supporting American Forests to help ensure
the existence of forest ecosystems and their benefits for future
generations."

ACE USA is supporting the following tree-planting programs:

-- Northern California - 64,000 trees will be planted to reforest
areas burned along the scenic Byway Highway 299 West that
connects the Northern Sacramento Valley with California's
Northwest Coast.

-- Southern California - The Mojave Desert Resource Conservation
District will plant 51,000 trees to replace forestry lost
