OPINION

Winfree Bonner, Jr., pled guilty to possession with intent to distribute cocaine and was sentenced to 150 months’ imprisonment. Bonner’s attorney has filed a brief in accordance with Anders v. Califor nia, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967). Counsel states that there are no meritorious grounds for appeal but raises an issue regarding Bonner’s career offender enhancement. Bonner has filed his own supplemental brief in which he contends that he received ineffective assistance of counsel at sentencing. In accordance with the requirements of Anders, we have considered the briefs on appeal and examined the entire record for meritorious issues. We find no error and dismiss.

The record on appeal discloses that Bonner waived his right to appeal in his plea agreement. This court reviews the validity of a waiver of appellate rights de novo. United States v. Marin, 961 F.2d 493, 496 (4th Cir. 1992). At his Fed.R.Crim.P. 11 hearing, Bonner was fully advised of the consequences of his plea, and he represented to the court that he understood the plea agreement, the charge to which he was pleading guilty, and the possible penalties he faced at sentencing. Bonner farther stated during the Rule 11 hearing that he fully understood the waiver of his right to appeal his sentence. We therefore find the plea agreement valid and enforceable. Because Bonner validly waived his right to appeal and because his sentence does not exceed the statutory maximum, we decline to address the issues raised in counsel’s Anders brief and in Bonner’s pro se supplemental brief.

This court requires that counsel inform his client, in writing, of his right to petition the Supreme Court of the United States for further review. If the client requests that a petition be filed, but counsel believes that such a petition would be frivolous, then counsel may move in this court for leave to withdraw from representation. Counsel’s motion must state that a copy thereof was served on the client. 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.
