Bounding Parameters used in FindFit[]

Is there a method to limit (bound) the search for a least-squares fit
with FindFit[] in Mathematica 5.2?

For example I am using FindFit[] to fit a decaying exponential of the
form P1 * Exp[-t/P2] + P3.  I know from the experiment that P3 is
smaller than the value Mathematica continues to find for that
parameter.  It would be great if there was a way to bound the search
for P3 to help Mathematica properly optimize P1 and P2.
