Variantly: "As the husband of the woman imposes (payment) upon him": I might think, as much as he likes! It is, therefore, "and he shall give it by pelilim," whereby we are taught he pays by word of judges, "pelilim" being judges, as in (Devarim 32:31) "And (now) our foes judge us" ("veoivenu pelilim"), and (I Samuel 2:25) "If a man sins against a man, then a judge judges ('pilel') him."
