CITGO RACING'S WATKINS GLEN II PREVIEW
Duno and CITGO Racing to Welcome Barbosa to 2nd Watkins Glen Race

August 7, 2006, Los Angeles, CA...Milka Duno and CITGO Racing head to
Watkins Glen International in Watkins Glen, NY for the second time this
season. Portugal's Joao Barbosa will share driving duties with Duno in the
#11 CITGO Pontiac Riley for the Crown Royal 200 at The Glen this Thursday
and Friday, August 10 and 11, 2006.

Barbosa will substitute for Duno's scheduled teammate Corvette Racing driver
Olivier Beretta. Increased tire competition in this year's Formula One World
Championship has resulted in Beretta, in accordance with his agreement with
Michelin, being called away from the Watkins race with Duno to perform in
his role as a Formula One test driver for Michelin.

Milka and CITGO Racing competed in June at The Glen for a six-hour race on
the 3.4-mile road course with both the DP (Daytona Prototype) and GT (Grand
Touring) classes racing together - which is the standard field for a Rolex
Series event. This event will be a two-hour race between DP's only - for
which a total of 26 have entered.

Milka Duno

"I really enjoy the all-DP format because all the cars on the track will be
more evenly matched and therefore much more competitive. In addition, since
there will be no GT's, we won't be slowed by them - nor can we use them to
our advantage - especially in overtaking situations.

While I'm sad that Olivier can't be with us at this race, I know he will be
back with us very soon and wish him great luck with the tire testing. At the
same time - it will be great to race with Joao. We've worked together in the
past in Europe and it was great fun and a valuable experience. I very much
welcome his participation and I'm sure he will fit in great with the CITGO
Racing team!"

Joao Barbosa

I'm very excited about joining CITGO Racing and SAMAX Motorsport for Watkins
Glen. I have known Peter [Baron, team owner] for a few years and I know what
a good job they are able to do. They have a good engine/chassis combination
and I'm looking forward to partnering with Milka and to try and give the
team a strong result. Milka has done incredibly well now and in the past
seasons. I know we have all the right ingredients to achieve a strong result
in a very competitive series!"
