Arkansas Electric Cooperatives, Tyson Foods and Walmart Foundation sponsor trip

Little Rock, Ark. – Oct. 18, 2012 – Nearly 170 World War II veterans will visit memorials
dedicated in their honor during a trip to Washington, D.C., on Saturday, October 20, as part of
the first official Honor Flight from Little Rock.

Thanks to major donations from Tyson Foods, Inc., the Walmart Foundation and the Electric
Cooperatives of Arkansas, two commercial jets have been chartered to fly 168 veterans free of
charge from Bill and Hillary Clinton National Airport in Little Rock, Ark., to Washington, D.C.,
and back. The group, which will include veterans as old as 94, will see the World War II
Memorial as well as other military memorials during their day in the nation’s capital.

“We are truly honored to be partnering with Tyson Foods and Walmart to provide this
experience for our state’s World War II veterans,” said Duane Highley, president and chief
executive officer for Arkansas Electric Cooperatives, Inc., (AECI) and Arkansas Electric
Cooperative Corporation (AECC). “The sacrifices they made as young men and women ensured
the freedoms we have today. We are proud to play a part in helping them see firsthand the
national memorial dedicated to their service.”

Flight organizers encourage the public to be at the Little Rock National Airport terminal at 7:30
p.m., Saturday evening, to be part of a special return reception for the veterans.

“This is a wonderful opportunity to show your support of these veterans from the ‘Greatest
Generation,’ as well as enjoy patriotic music and flag waving,” said Melissa Lee, a Tyson Foods
attorney who is chair of the company’s Veterans Business Resource Group (VBRG), which has
been actively involved in supporting the Honor Flight program.

The Arkansas Army National Guard will provide the Color Guard and the Army Quartet Band.
The State of Arkansas Adjutant General will meet the flights in D.C. and travel with the veterans
on the tour of their memorial.
