I dont read it that way actually.. I see it as, it will terminate on the 15th if 30 days is given. The "Thereafter" to me means, "Thereafter this Pilot, we go to the National Roll out" . Its saying, "after" this pilot is successful, and NOT cancelled, "There after we shall roll out............"
and terminate on or about January 15, 2006. Thereafter, unless 30 days notice is given to the contrary......."
