With difficulty!

There is far too little here to go on, and this seems an odd question 
unless it is homework (why dictate a problem-strewn method of solution 
if this is a real problem?)

The real issue is how to bootstrap nonlinear regression, and you will 
find that discussed in all good books on the subject, such as Venables & 
Ripley and Davison & Hinkley.  It is not trivial and the solutions are 
not altogether satisfactory ....
