USG Corporation`s L&W Supply Subsidiary Wins Highest Partners of Choice Award from David Weekley Homes

CHICAGO--(Business Wire)--
For the third consecutive year, USG Corporation`s (NYSE: USG) L&W Supply Co.
subsidiary Seacoast Supply received the prestigious Partners of Choice Award
from David Weekley Homes, a privately held home builder based in Houston, Texas.
Seacoast Supply achieved an "AA" rating, earning an "A" rating in both service
and quality for the second year in a row after receiving an "A" rating in 2007.

Seacoast Supply is the only drywall or roofing supplier to earn the "AA" rating
in the award`s six-year history and is one of only 11 companies to earn the
coveted "AA" rating. A total of 150 companies participate in the award program.

"We are honored to receive this award from David Weekley Homes, and hold an "AA"
rating for the second consecutive year," said Brendan Deely, president and chief
executive officer of L&W Supply. "The Partners of Choice Award is a testament to
Seacoast Supply and the employees that are dedicated to providing the best
quality building solutions and service in the industry."

The awards are based on the David Weekley Homes` National Trading Partner
Survey, a running quarterly review provided by nearly 1,000 David Weekley
employees. Suppliers are rated on quality, service, price and relationship
response on a 1-10 scale. The scores for each company are averaged, and then
ranked with all others that participate. Alpha rankings ranging from "A" to "F"
are assigned in 20-percent increments. Receiving an "A" for both quality and
service in the same year is rare, with the "AA" Partners of Choice Award being
the highest possible ranking. The awards are presented to suppliers who
maintained either an "AA" rating for both quality and service, or an "A" rating
in either quality or service for the previous twelve months.

"It is extremely difficult to achieve an "A" rating in both quality and service
for three months, let alone 12, but Seacoast Supply has earned that honor
twice," said Bill Justus, vice president of Supply Chain Services for David
Weekley Homes, who developed the quarterly survey and ranking methodology six
years ago. "A world class supplier is willing to put their products and services
up against anybody, anywhere, anytime. And that is what Seacoast Supply has done
two years running."

"This award reflects our ongoing commitment to David Weekley Homes and our
customers," said Tim Mahaffey, general manager, operations, Florida Region of
L&W Supply. "It is a thrill and honor for the whole Seacoast Supply team to be
recognized once again for this prestigious award."
