Benjamin L. Doyle seeks to appeal the district court’s orders: (1) dismissing his claims against the Department of Corrections and Craven Correctional Institution as frivolous; and (2) denying his motion for appointment of counsel. This court may exercise jurisdiction only over final orders, 28 U.S.C. § 1291 (2000), and certain interlocutory and collateral orders, 28 U.S.C. § 1292 (2000); 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 orders Doyle seeks to appeal are neither final orders nor appealable interlocutory or collateral orders. Accordingly, we dismiss the appeal for lack of jurisdiction. We deny Doyle’s motion for appointment of counsel. 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
