Quarles Petroleum Incorporated is pleased to announce that it has purchased the fleet fueling business
of Woodfin Heating, Inc., making Quarles the new operator of all U.S. Fleet and Watchcard fueling
locations. For now, those locations will continue to operate as a separate system managed by Quarles.
However, once the software and hardware of the two companies are fully integrated, this addition will
give our customers access to the largest unattended commercial fueling network on the East Coast and
bring many other advantages to Watchcard, U.S. Fleet, and Quarles customers. This exciting change
expands Quarles’ unattended fueling network to 125 sites throughout Pennsylvania, Delaware,
Maryland, Virginia, West Virginia, and North Carolina.

“We’re excited about the acquisition as it will ultimately provide greater fueling convenience to our busy
customers,” said Quarles Petroleum President, Ben Wafle. Quarles is dedicated to the continued
development of clean and convenient fuel sites along the Mid-Atlantic.

All Quarles Fleet Fueling customers benefit from exceptional customer service, fuel card security, online
account management and product enhancements. Watchcard and U.S. Fleet also have a proud history
of providing excellent service. We believe the combination of these two networks will allow us to build on
the strengths of both organizations for the ultimate benefit of all our customers. We anticipate the
transition and integration of the new sites to be completed by early 2012.
