Unpublished opinions are not binding precedent in this circuit.2 PER CURIAM: Ricky Nelson Simpson appeals the 96

- month , below

- Guidelines sentence imposed after he ple d guilty, pursuant to a plea agreement, to one count of conspiracy to distribute and possess with intent to distribute 28 grams or more of cocaine base and 500 grams or more of cocaine, in violation of 21 U.S.C. §§ 841(b)(1)(B) , 846 (2012). Counsel has fi led a brief, pursuant to Anders v. California , 386 U.S. 738 (1967), in which she challenges the substantive reasonableness of Simpson’s sentence, but recognizes that Simpson waived his right to appeal his sentence in his plea agreement. Simpson has filed a pro se supplemental brief asserting that counsel was ineffective , thereby resulting in the denial of his due process rights . The Government has filed a motion to dismiss the appeal based on the appellate waiver in Simpson’s plea agreement. We affirm in part, and dismiss in part. A defendant may waive the right to appeal if that waiver is knowing and intelligent. See United States v. Poindexter , 492 F.3d 263, 270 (4th Cir. 2007). Our independent review of the record supports the conclusion that Simpson voluntarily and knowingly waived his right to appeal his conviction and sentence. Thus, we conclude that the waiver is valid and enforceable.3 However, even a valid waiver does not waive all appellate claims. Specifically, a valid appeal waiver does not preclude a challenge to a sentence on the ground that it exceeds the statutory maximum or is based on a constitutionally impermissible factor such as race, arises from the denial of a motion to withdraw a guilty plea based on ineffective assistance of coun sel, or relates to claims concerning a violation of the Sixth Amendment right to counsel in proceedings following the guilty plea. See United States v. Johnson , 410 F.3d 137, 151 (4th Cir. 2005); United States v. Craig , 985 F.2d 175, 178 (4th Cir. 1993). Moreover, the appellate waiver in Simpson’s plea agreement did not waive: (1) any sentencing challenges he may have if his sentence was in excess of the applicable advisory Guideline s range established at sentencing ; or (2) ineffective assistance of counsel or prosecutorial misconduct claims not known to Simpson at the time of his guilty plea

. Simpson’s sentence is below the Guidelines range established at sentencing and, thus, counsel’s claim is squarely foreclosed b y the appellate waiver . Accordingly, we grant the Government ’ s motion to dismiss the appeal , in part

.4 In accordance with Anders , we have reviewed the record for any potentially meritorious, unwaived issues , * and we have found

none . We therefore dismiss the appeal in part and affirm in part. This court requires that counsel inform Simpson , in writing, of h is right to petition the Supreme Court of th e United States for further review. If Simpson requests that a petition be filed, but counsel believes th at such a petition would be frivolous, then counsel may move this court for leave
to withdraw from representation. Counsel’s motion must state that a copy thereof was served on Simpson . We dispense with oral argument because the facts and legal contentio ns are adequately prese nted in the materials before this court and argument would not aid in the decisional process.

AFFIRMED IN PART; DISMISSED IN PART

* T o the extent Simpson suggests that counsel provided ineffective assistance, we conclude that ineffective assistance does not conclusively appear on the record. See United States v. Baldovinos , 434 F.3d 233, 239 (4th Cir. 2006).
