SDT Waste and Debris Services, LLC Acquired by IESI Corporation

Combination Expected to Enhance SDT's Growth and Service in Louisiana

Press Conference at 1:30 pm, June 2, 937 Esplanade Avenue

CHALMETTE, LOUISIANA--(Marketwire - June 2, 2011) - IESI Corporation
("IESI") and SDT Waste and Debris Services, LLC ("SDT") jointly announced
today that SDT will join IESI, a subsidiary of Progressive Waste Solutions
Ltd. ("Progressive Waste Solutions"). Terms of the deal were not disclosed.

SDT will retain its name and brand and continue to operate out of its
Chalmette and Independence, Louisiana headquarters as a Progressive Waste
Solutions company. SDT President Sidney D. Torres, IV, has been retained as
a consultant and has resigned his position as president of the company. Tom
Martyn, District Manager for IESI and based in New Orleans, will oversee the
operations.

"My decision to join forces with IESI, a part of Progressive Waste
Solutions, was an easy one. Over the last five years, they have been our
strongest competitor in the State of Louisiana and they value their
employees and deliver the highest quality of service, just as SDT does. I
have every confidence that our customers will never notice the difference,"
said Mr. Torres.

Mr. Martyn commented, "We have the greatest respect for Mr. Torres and the
SDT team. SDT's success has been built on a foundation of excellent customer
service and IESI shares that commitment. From our drivers and helpers to our
customer service representatives, we take pride in serving communities
throughout Louisiana. We look forward to joining with the SDT team and
delivering seamless service together."

All SDT contracts and agreements are unaffected by the merger. SDT will
remain the municipal waste contractor for the New Orleans French Quarter and
downtown as well as the waste contractor for the parishes of Iberia, East
Feliciana, St. Bernard, St. Charles, Tangipahoa and the town of
Independence.

SDT's 250 employees were notified of the merger shortly before the
announcement today. "The number one reason that SDT expanded to 24 cities
and parishes in five years has been because of the hard work and dedication
of our employees. They paid attention to every detail on their routes,
maintained clean trucks, neat uniforms and positive attitudes," Mr. Torres
said. "IESI is in a position to continue SDT's growth and increase the level
of service that SDT currently provides to its customers."

Progressive Waste Solutions is the third largest non-hazardous solid waste
solutions provider in North America, providing services to more than four
million commercial, industrial and residential customers in twelve states
and the District of Columbia in the United States and six provinces in
Canada.
