It's here:

 
http://www.ordnancesurvey.co.uk/oswebsite/opendata/licence/docs/licence.pdf

Unfortunately it does not, as far as I can see, allow anybody who has 
used, or plans to use, OS OpenData to sign the CTs as things stand 
because it requires:

Which is clearly in conflict with the CTs which require you to grant 
OSMF a license to sublicense any data you upload under a license of 
their choosing subject only to a constraint that the license they choose 
is "open and free" which clearly does not restrict their choice to 
licenses that would pass on the attribution requirement.
