What are the two numbers?

Sam and Peter, are told that integers x and y have been chosen such that 1 < x < y and x+y < 100.  Sam is given the value x+y and Peter is given the value xy.  They then have the following conversation:

Peter:  I cannot determine the two numbers.
Sam:  I knew that.
Peter:  Now I can determine them.
Sam:  So can I.
