A frame matroid is any submatroid of a matroid in which each point belongs to a line spanned by a fixed basis. A biased graph is a graph with certain polygons called balanced; no theta graph contains exactly two balanced polygons. It is proved that certain matroids associated with biased graphs are identical with the finitary frame matroids.
