Deactivate exhibit from phpmyadmin

I updated succesfully at the 2.0 version of wordpress which is very nice. Then I just re-activate exhibit but now i have problem in enter the blog so how can i deactivate directly from phpmy admin? this is the string i have [a:5:{i:0;s:0:””;i:1;s:24:”exhibit10TOGLIQUESTO.php”;i:2;s:19:”image-headlines.php”;i:3;s:24:”the-excerpt-reloaded.php”;i:4;s:9:”top10.php”;}]
