[Tex/LaTex] ACM SIG Proceedings: 6 authors total- 3 shared affiliation, also 2 shared affiliation

acmauthor-numberformatting

On the website for the ACM SIG Proceedings Template, there is an example where three authors all share the same affiliation (See number 17).

However, my situation is a bit different, I am part of a team of two other authors, we are all from the same Uni, also there is a team of two from a second University, and finally the third author who is from a different Uni entirely- but is by all accounts the most important author and should be first.

Ideally I would want it to look something like:

enter image description here

I tried the following code which results in a horrendous error: 

\numberofauthors{6}
% Three authors sharing the same affiliation.
    \author{
      \alignauthor Ben King\\      
      \email{king@cs.berkeley.edu}
%
      \alignauthor Georgia Tobin\\     
      \email{tobin@cs.berkeley.edu}
%
      \alignauthor Gerald Murray\\    
      \email{murrray@cs.berkeley.edu}
%
      \sharedaffiliation
      \affaddr{Department of Electrical Engineering and Computer Science }  \\
      \affaddr{University of California, Berkeley }   \\
      \affaddr{Berkeley, CA 94720-1776 }\\

            \alignauthor Ben King\\      
      \email{king@cs.berkeley.edu}
%
      \alignauthor Georgia Tobin\\     
      \email{tobin@cs.berkeley.edu}
%
      \alignauthor Gerald Murray\\    
      \email{murrray@cs.berkeley.edu}
%
      \sharedaffiliation
      \affaddr{Department of Electrical Engineering and Computer Science }  \\
      \affaddr{University of California, Berkeley }   \\
      \affaddr{Berkeley, CA 94720-1776 }
          }

Does anyone know how I could render the authors to appear as I've made in that toy example, the photo?

UPDATE*

The following is also awful:

\numberofauthors{5}
\author{
      \alignauthor Ben King\\      
      \email{king@cs.berkeley.edu}
      \alignauthor Georgia Tobin\\     
      \email{tobin@cs.berkeley.edu}
      \alignauthor Gerald Murray\\    
      \email{murrray@cs.berkeley.edu}
      \sharedaffiliation
      \affaddr{Department of Electrical Engineering and Computer Science}  \\
      \affaddr{University of California, Berkeley }   \\
      \affaddr{Berkeley, CA 94720-1776 }\\
      \\
      \alignauthor

    \email{\{g.buscher, f.bensberg\}@hs-osnabrueck.de}
}
