Genetics to certain milestone payments. Response Genetics earned its first
milestone payment of $500,000 in July of 2012 for submission of the first
Premarket Approval ("PMA") and its second milestone payment of $500,000 in May
2013 for the FDA's approval of the PMA.Response Genetics has now earned its

yet another example of the long-standing and mutually-beneficial relationship
between Response Genetics and GSK.All of us at Response Genetics take pride
