\theexmp is supposed to give you the representation of the `exmp' counter.  
I think this is closer to what you want.

\newcounter{exmp}[chapter]
\renewcommand*\theexmp{\thechapter.\arabic{exmp}}
\newcommand*\bex{%
   \par \vspace{11pt}%
   \noindent
   \refstepcounter{exmp}%
   \textbf{Example \theexmp}%
   \par \vspace{11pt}%
   \noindent \begin{inpar}%
     \setlength\parskip{2pt plus 0.5pt}%
}

You may note that \bf has been obsolete for more than ten years.
