I would guess that when you do Exec xterm, the environment you started X
with is being inherited, and when you do Exec exec xterm, the
environment is being cleared. Try putting xterm*loginShell: true in
your ~/.Xresources (or ~/.Xdefaults if appropriate), or starting xterm
like: Exec exec xterm -xrm 'loginShell: true'
