CITGO RACING'S MID-OHIO PREVIEW

Duno teams again with five-time Le Mans class winner Olivier Beretta

June 21, 2006, Los Angeles, CA...Milka Duno, for the 2nd time this season,
will team with Corvette Racing driver Olivier Beretta for Round 9 of the
Rolex Sports Cars Series Championship at the Mid-Ohio Sports Car Course in
Lexington, OH June 23 -25, 2006. Beretta just scored his fifth class win at
the 24 Hours of Le Mans in Le Mans, France last weekend.

Duno and Beretta paired for the first time at Phoenix International Raceway
last month where they narrowly missed the top-ten with an 11th place finish.

The hard work of the drivers and crew has been delivering strong
performances with each successive outing and they hope to carry that
momentum with them to Mid-Ohio. Duno brings along a previous 2nd place
finish at the Lexington, OH circuit and Berretta arrives to the track fresh
from a class win with Corvette Racing at Le Mans last weekend.

Milka Duno
"First of all - congratulations to Olivier for his win at Le Mans! It will
be great to race with him with all that positive energy he will bring to our
effort. We've been working very hard and the results of that are showing
with each and every race. I can't wait to hit the track with him and the
crew - and I know we'll all be giving 100% toward a great finish."

Olivier Beretta
"Phoenix was my first race [with Milka and CITGO Racing], so now I know the
team and my teammate. We did well in Phoenix and hopefully we will do even
better in Mid-Ohio. I am very happy that CITGO and the SAMAX team gave me an
opportunity to join the DP class, and I will do my best to help the team and
Milka. I have never run a prototype in Mid-Ohio, but I think it will suit
the car because it is a good car to drive. I will know as soon as I run a
few laps. All of the drivers are very professional and the track is
relatively easy to learn, so after four or five laps, everyone will be
comfortable."

Race action for the Rolex Series will begin on Saturday, June 24 at 530pm
EDT and will be televised tape-delayed the following day - Sunday, June 25 -
on the SPEED Channel. Live timing and scoring will be available during the
