_______________________________________
The following rule applies, as mentioned within the question, and as quotated DIRECTLY from THIS VERY QUESTION:
"<span>Group VII. When the word has an immediate -tion form, -ible is used.</span>"
______________________________________
Note: The word, "exhaust" ; does, in fact have an "immediate -tion form" ;
since the word, "exhaust" ; ends with the letter, "t" ; and since the word, "exhaust" ; has an "immediate -tion" form, which is the word, "exhaustion" ; then "Group VII" applies.

The word is "exhaustible" ; (note that the ending is: "-ible").
Group: VII .
