exprnd is part of the Statistics Toolbox, which is an optional product for Commercial and Academic licenses.
The Statistics Toolbox is included in the Student Version licenses but the Toolbox might not be installed by default. I note that you are using R2008b, which has the only Student Version release (so far) that ends in 'b', so you might be using Student Version.

I don't think I'd be giving away valuable secrets by telling you that exprnd is a relatively simple function:
>> rng(0)
>> exprnd(5,2,3)
ans =
1.0245 10.3184 2.2915
0.4947 0.4530 11.6374
>> rng(0)
>> -5*log(rand(2,3))
ans =
1.0245 10.3184 2.2915
0.4947 0.4530 11.6374
