[OS X TeX] environment question

Hi.
I have created an environment called "offset", which I use for
material that needs to be offset from the main text flow. Here is a
small LaTeX file that illustrates its definition and use.
<snip>
\documentclass{article}
\newenvironment{offset}[1]%
{\bigskip\hrule\nopagebreak[4]\bigskip\nopagebreak[4]\noindent%
\textbf{#1}\nopagebreak\par\medskip\nopagebreak\noindent}%
{\nopagebreak[4]\bigskip\hrule\bigskip}
\begin{document}
My first example is
\begin{offset}{Addition rule (elementary version)}%
Given two disjoint events, $E_1$ and $E_2$, with associated
probabilities P($E_1$) and P($E_2$), the probability of $E_1$
\emph{or} $E_2$ occurring is equal to
to $P(E_1) + P(E_2)$. That is,
\[P(E_1 \cup E_2) = P(E_1) + P(E_2)\]
if $E_1$ and $E_2$ are disjoint.
\end{offset}
As you can see, this looks pretty good.
My second example is:
\begin{offset}{Addition rule (general version)}%
Given events $E_1$ and $E_2$, with associated
probabilities $P(E_1)$ and $P(E_2)$, the probability of $E_1$
\emph{or} $E_2$ occurring is
\[P(E_1\cup E_2) = P(E_1) + P(E_2) - P(E_1 \cap E_2)\]
\end{offset}
That extra space between the math display and the horizontal line is
ugly.
\end{document}
</snip>
Note the following:
(1) The comment about the extra (vertical) space.
(2) I need to put a % after the argument, to avoid an extra horizontal
space.
Any ideas how to fix this? Is there something pre-existing that I can
use instead?
Thanks.
