 C*-algebras associated to semigroups provide important 
examples in operator algebras. Nica defined semigroups that are part of  a quasi-lattice ordered pair and associated C*-algebras to them. The 
motivation for his construction was to study C*-algebras associated to 
the free monoid in finitely many generators. Laca and Raeburn proved a  uniqueness result for C*-algebras associated to quasi-lattice ordered 
pairs. For a class of semigroups that includes the quasi-lattice ordered 
ones but also semigroups with non trivial units, we provide a similar 
uniqueness result. This is joint work with N. Brownlowe and N. Stammeier.
