Using Offset inside a Vlookup

Can anyone help me figure out how to use the offset function inside a vlookup?

eg. if this was the table (table also attached)

Row 1: Group 1 | Parameter 1 | A B C
Row 2: | Parameter 2 | D E F
Row 3: | Parameter 3 | G H I

How would i vlookup "Group 1" and return "F" ?

Appreciate any help.

Perhaps something like this:

=INDEX($C$2:$F$4,1+MATCH("Group 1",A2:A4,0),3)
