Frank Esquivel appeals from his conviction and 264-month sentence and the order of forfeiture * imposed following Esquivel’s guilty plea to one count of conspiracy to distribute and possess with intent to distribute cocaine base and cocaine, 21 U.S.C. § 846 (2000). Finding no merit to his appeals, we affirm.

Esquivel claims that his guilty plea was not knowing and voluntary because, although he stipulated in his plea agreement “that the readily provable quantity of the controlled substance to be used for the purpose of establishing the base offense level is ... more than 50 kilograms of cocaine,” he did not realize that he could be sentenced based on a quantity exceeding fifty kilograms of cocaine. We find that the district court conducted a thorough inquiry pursuant to Rule 11 of the Federal Rules of Criminal Procedure. Absent extraordinary circumstances, an appellant is bound by his statements at the plea hearing. Beck v. Angelone, 261 F.3d 377, 395-96 (4th Cir. 2001). The record in this case does not support Esquivel’s claim that he was confused about the consequences of his plea.

Accordingly, we affirm. 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.
