My own preference for this type of thing is to use a Select statement.
I'd also change the name to Uppercase so there was no mistakes in the

This would look something like...
For Each wSht In Worksheets
Select case Ucase(wSht.Name)
Case "SHEET1", "SAMPLE"
'Do Nothing
Case Else
'Code for rest of sheets
End Select
Next wSht
