Ignacio Pineda-Bermudez appeals his conviction and sentence following his unconditional guilty plea to possession with intent to distribute cocaine hydrochloride, in violation of 21 U.S.C.A. §§ 841(a)(1), (b)(1)(B) (West 1999). Because Pineda Bermudez waived his right to challenge pre-trial suppression issues when he failed to enter a conditional plea pursuant to Fed.R.Crim.P. 11(a)(2), we affirm. See Fed.R.Crim.P. 11(a)(2); United States v. Willis, 992 F.2d 489, 490 (4th Cir. 1993). 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.

AFFIRMED.
