[ULPIANUS libro octauo disputationum. ] §20.6.3.prSi res distracta fuerit sic, nisi intra certum diem meliorem condicionem inuenisset, fueritque tradita et forte emptor, antequam melior condicio offerretur, hanc rem pignori dedisset, Marcellus libro quinto digestorum ait finiri pignus, si melior condicio fuerit allata, quamquam, ubi sic res distracta est, nisi emptori displicuisset, pignus finiri non putet.
[ULPIAN, book 8 of Disputations.] If a thing has been sold on the condition that "unless a better term is found within a certain day," and it has been delivered, and perchance the buyer, before a better term was offered, had given this thing in pledge, Marcellus in the fifth book of his Digests says that the pledge is terminated if a better term has been brought, although he does not think that the pledge is terminated when a thing has been sold on the condition "unless it should displease the buyer."
