AGL Resources and Piedmont Natural Gas Reach Agreement to Restructure
Ownership Interests in SouthStar Energy Services
AGL Resources Will Purchase 50 Percent of Piedmont's Current Interest in
SouthStar for $57.5 Million

ATLANTA, July 30 /PRNewswire-FirstCall/ -- AGL Resources Inc. (NYSE: AGL)
subsidiary Georgia Natural Gas Company (GNGC) and Piedmont Energy Company, a
subsidiary of Piedmont Natural Gas (NYSE: PNY), today announced an agreement
to restructure the two firms' ownership interests in SouthStar Energy Services
(SouthStar). Under the terms of the agreement, effective January 1, 2010, AGL
Resources will purchase an additional 15 percent ownership share in SouthStar
from Piedmont for $57.5 million. As a result, AGL Resources will have an 85
percent ownership in the business and will be entitled to 85 percent of its
annual earnings, while Piedmont will retain a 15 percent earnings and
ownership share in SouthStar after the sale.

The agreement, which has been approved by both companies' boards of directors,
also resolves issues concerning AGL Resources' option to purchase Piedmont's
ownership interest in SouthStar. As part of the agreement, the pending
lawsuit in the Delaware courts will be dismissed and AGL Resources will not
have any further option rights to Piedmont's remaining 15 percent ownership
interest.

The agreement is subject to the approval and consent of the Georgia Public
Service Commission.

"Piedmont has always been a very good partner, and we look forward to
continuing our longstanding relationship with them," said John W. Somerhalder
II, AGL Resources' Chairman, President and CEO. "We reached an agreement that
works well for both companies in terms of providing certainty around the
partnership structure and creating value for our respective shareholders."

Commenting on the agreement, Piedmont's Chairman, President and CEO, Thomas E.
Skains said, "We are happy to conclude this agreement with AGL and believe our
strategic interests in SouthStar will be more closely aligned as a result.
This has been a good partnership for both of our companies and we value the
relationship we have with AGL. The nature of this agreement, which will
simplify and strengthen our joint venture involvement in SouthStar, also
reaffirms the core focus of our business as the safe and efficient
distribution of natural gas to our growing utility markets in North Carolina,
South Carolina, and Tennessee."
