Analytical two-loop contributions to soft masses of sfermions are derived inthe Extended GMSB (EGMSB) model with one superpotential coupling between matterand messenger superfields. Analytical results allows to study in detail thewhole range of the ratio $F/M^2$ of the spurion $F$-term, $F$, to the messengerscale $M$. It is shown that if $F/M^2$ is of the order of $1$, then one- andtwo-loop contributions to soft masses are of the same magnitude and theirinterplay leads to novel sfermion mass patterns.
