CITGO RACING'S SONOMA PREVIEW
Patrick Carpentier with Milka Duno and CITGO Racing for Northern California Event

August 21, 2006, Los Angeles, CA...Milka Duno and CITGO Racing welcome open
wheel standout Patrick Carpentier to their effort for the penultimate race
of the 2006 Rolex Sports Car Championship at Infineon Raceway in Sonoma, CA.
this August 24-26. The 2-hour, 45-minute race will be on Saturday, August 26
starting at 3:00pm PDT.

This will be Duno's first partnering with Carpentier - but not Carpentier's
first time behind the wheel of the Daytona Prototype. He raced with Cheever
Racing in the #39 Daytona Prototype at the 2006 Rolex 24 At Daytona - where
in his first-ever sports car endurance race - he led for a total of 55 laps.
A terminal mechanical failure ended the effort with only two hours remaining
- resulting in an 11th place-in-class finish.

Carpentier won the Player's/Toyota Atlantic Championship in 1996 with eight
poles and a record nine wins in twelve starts. He then headed straight to
Championship Auto Racing Teams in 1997 and earned "Rookie of the Year"
honors. From 1998 to 2002 he earned three wins, three poles, twelve podiums
and in 2002 finished third in the championship and was presented with the
Greg Moore Legacy Award. In 2003 and 2004 Carpentier, now in the Champ Car
World Series, scored two wins, two poles, nine podiums and finished the 2003
season third in the championship and the 2004 season fifth in the
championship. In 2005, Carpentier finished tenth in the Indy Racing League
Championship.

Duno's previous experience at Sonoma includes an LMP 675 class win in the
American Le Mans Series in 2000 in the Reynard 01Q/Judd Le Mans Prototype.

Milka Duno
"I'm a big fan of Patrick's and have followed his achievements since he
earned the Toyota Atlantic Championship. It will be great to have him with
us for this race and we'll do everything we can to make him feel welcome.

This will be the first race for the Daytona Prototypes at Sonoma and that
means we'll have no background data for the car on this track. It will
increase our challenge - but it will be the same for everyone else. I've
raced here before, so that will be helpful. It will be interesting to hit
the circuit in the #11 CITGO Pontiac Riley and see how it feels with this
car.

We've been very competitive all season and deserve to be on the podium. I've
been on the podium at Sonoma and it's a great feeling. Hopefully we can earn
one this time out!"

Patrick Carpentier
"I am extremely delighted to start racing again. It was good to take a few
months off and spend some time with my kids on the ranch, but now it is time
to go back to racing. This is a track I enjoyed last year with the IRL and
I'm looking forward to going back to it. I want to thank the team and its
affiliated sponsors for giving me this opportunity."

The three-day race event will have the team practicing on Thursday
afternoon, practicing and qualifying on Friday, and racing on Saturday
afternoon at 3pm PDT - with live timing and scoring, plus audio in English
and Spanish, available at www.grandamerican.com. The race will be broadcast
tape-delayed the next day on Sunday, August 27 at 3pm EDT on the SPEED
