OPINION

Edward D. Singletary appeals his convictions and 300 month sentence imposed after he pled guilty to possession with intent to distribute 50.8 grams of crack cocaine, in violation of 21 U.S.C.A. § 841 (West 1999 & Supp. 2001), and possession of a firearm by a convicted felon, in violation of 18 U.S.C.A. § 922(g)(1) (West 2000). Singletary’s attorney has filed a brief in accordance with Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), raising as a potential claim the effectiveness of Singletary’s first counsel but stating that, in his view, there are no meritorious grounds for appeal. Singletary has filed a pro se supplemental brief. We dismiss.

At the outset, we find that Singletary knowingly and voluntarily waived his right to appeal his convictions and sentence on any ground, except ineffective assistance of counsel, prosecutorial misconduct, a sentence in excess of the statutory maximum, or a sentence based upon an unconstitutional factor.* See United States v. Brown, 232 F.3d 399, 402-03 (4th Cir. 2000) (providing standard for reviewing enforceability of waiver of right to appeal). Singletary’s ineffective assistance of counsel claim, therefore, is not barred by the waiver. However, we decline to review Single-*300tar/s claim that he was denied effective assistance of counsel because the face of the record does not conclusively show that counsel provided ineffective representation. See United States v. Richardson, 195 F.3d 192, 198 (4th Cir. 1999) (providing standard and noting that ineffective assistance of counsel claims generally should be raised by motion under 28 U.S.C.A. § 2255 (West Supp. 2001)), cert. denied, 528 U.S. 1096, 120 S.Ct. 837, 145 L.Ed.2d 704 (2000).

As required by Anders, we have examined the entire record and find no meritorious issues for appeal. Accordingly, we dismiss the appeal. 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.
