In a large bowl, toss the fruit, sugar and flour. Pour into a greased 13-in. x 9-in. baking dish. For topping, in a bowl, combine the brown sugar, flour, oats and cinnamon. Cut in butter until mixture resembles coarse crumbs. Sprinkle over fruit mixture.
Bake at 350° for 60-65 minutes or until fruit is tender and topping in golden brown.
