st: How to Graph - Exponential model

Dear All:

I have performed the non-linear least squares estimation method of regression, using the exponential model y = b1*b2^x.

I would like to create a graph of this equation on a scatterplot of my data, along with 95% confidence interval lines.  

I am able to create the scatterplot but am having difficulty graphing the regression exponential equation line.  I have tried twoway graphs, but the fit plot options of linear prediction and quadratic prediction with confidence intervals obviously does not match the exponential model.  

Thanks in advance!
