Temperature control-step response for a transfer function

Hi,

Having some real problems creating the correct step response figure for the following transfer function:

G(s) = e^(-ts) * H/(1+Ts)

so far I can create the step response figure for a simplified transfer function G(s) = H/(ts+1)(Ts+1) by;

in matlab main window:
H = 2.08
T = 0.45
t = 0.12
gopen = tf([H],[t*T,T+t,1])
gclose = feedback(gopen,1)
step(gclose)

however i'm not sure how to create 'gopen' for the first more accurate transfer function??

i've tried the following but I have no idea which one (if any) is correct!

gopen = tf([exp(-t),H],[T,1])

gopen = tf((exp(-t))*[H],[T,1])

and

gopen = tf([exp(-t)],[T,1])


any help would be really appreciated.

Thanks

Dan
