Pure Goldie Dimensions for Exactly Definable Categories

It is shown that if A is an object in an exactly definable category C such that A has finite pure Goldie dimension and that every pure monomorphism A → A is an isomorphism, then its endomorphism ring EndC(A) is semilocal. Also, it is proved that every subobject of a pure quotient finite dimensional pure injective object of an exactly definable category has a semilocal endomorphism ring.
