Yoko Mizuno Benda appeals the district court’s order denying her motion to dismiss an indictment and her motion for disclosure of grand jury materials. We dismiss the appeal for lack of jurisdiction because the order is not appealable. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (1994), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (1994); Fed.R.Civ.P. 54(b); Cohen v. Beneficial Indus. Loan Corp., 337 U.S. 541, 69 S.Ct. 1221, 93 L.Ed. 1528 (1949). The order here appealed is neither a final order nor an appeal-able interlocutory or collateral order. See United States v. Ferguson, 246 F.3d 129, 138 (2nd Cir. 2001).

We dismiss the appeal as interlocutory. We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before the court and argument would not aid the decisional process.

DISMISSED.
