\documentclass{tlc3exa}
\pagestyle{empty}
\setcounter{page}{6}
\setlength\textwidth{124.20126pt}
\pagestyle{origplain} % example class does not show page numbers with ``plain'' pagestyle
\setcounter{page}{1}
\tolerance=4000 % examples is very narrow ...
\usepackage{microtype} % so let's try to make this a bit better
%--------------------------------------
% For the book example we have to do some faking here. By default the
% hpos and vpos are at the center of the page and so we mimic this
% here. This is why we load the package internally and reset the keys:
\setlength\textheight{94pt}
\setlength\oddsidemargin{0pt}
\setlength\evensidemargin{0pt}
\RequirePackage{draftwatermark}
\DraftwatermarkOptions{
hpos=\dimexpr 1in + .5\textwidth ,
vpos=\dimexpr 1in + \topmargin + \headheight+\headsep+ (\textheight+\footskip)/2 ,
}
% So the above should not be copied into your own document preamble.
