Defendant Wilmer Leyva-Matos pleaded guilty to possessing marijuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1) and conspiring to possess marijuana with intent to distribute in violation of 21 U.S.C. § 846. In his plea agreement, Defendant waived his right to appeal. The district court rejected certain stipulations in Defendant’s plea agreement and sentenced him to twenty-six months imprisonment, followed by two years of supervised [1215]*1215release. Defendant appeals, alleging the district court improperly considered certain information he provided the Government with the understanding that it would not be used against him. We have jurisdiction under 28 U.S.C. § 1291 and 18 U.S.C. § 3742(a). See United States v. Hahn, 359 F.Bd 1315, 1322, 1324 (10th Cir.2004) (en banc) (holding that we have jurisdiction under 28 U.S.C. § 1291 over sentencing appeals “even when the defendant has waived his right to appeal in an enforceable plea agreement”). Because we conclude Defendant’s appellate waiver is valid and enforceable, we dismiss this appeal without addressing the merits.

In 2008, Border Patrol agents stopped Defendant and co-defendant Viktor Elizalde at a checkpoint on Interstate 10 west of Las Cruces, New Mexico. During a consensual search of the vehicle, Border Patrol agents discovered an unloaded handgun in the vehicle’s center console and 26.2 kilograms of marijuana hidden behind the car’s trim panels. They also discovered ammunition for the handgun in Elizalde’s bag. Elizalde waived his Miranda rights and admitted the gun was his. Further investigation revealed the car belonged to Defendant’s parents.
After a New Mexico grand jury returned an indictment against Defendant for one count of possessing marijuana with intent to distribute in violation of 21 U.S.C. § 841(a)(1) and one count of conspiring to possess marijuana with intent to distribute in violation of 21 U.S.C. § 846, Defendant entered into an agreement to plead guilty to both charges. He also agreed to provide information about the crimes with which he and Elizalde were charged in exchange for the Government’s promise that it would not use any of the information he provided against him. See U.S.S.G. § 1B1.8 (providing that “[wjhere a defendant agrees to cooperate with the government by providing information concerning unlawful activities of others, and as part of that cooperation agreement the government agrees that self-incriminating information provided pursuant to the agreement will not be used against the defendant, then such information shall not be used in determining the applicable guideline range, except to the extent provided in the agreement”). In the plea agreement, the Government agreed to certain stipulations that, if accepted by the district court, would reduce the range of Defendant’s sentence under the Sentencing Guidelines. The Government also stated, however, that it did not agree to recommend a specific sentence nor to support, oppose, or not oppose any sentence proposed by the Defendant. See Fed. R.Crim.P. 11(c). Additionally, Defendant waived his appeal rights and agreed that the district court could accept or reject the stipulations in its discretion. The plea agreement provides:
The United States and the defendant understand that the above stipulations are not binding on the Court and that whether the Court accepts these stipulations is a matter solely within the discretion of the Court after it has reviewed the presentence report. The defendant understands and agrees that if the Court does not accept any one or more of the above stipulations, the defendant hereby waives the right to appeal the Court’s rejection of such stipulations.
R. Vol. 1 at 11 (emphasis added). A section titled “Waiver of Appellate Rights” also provides:
The defendant is aware that 28 U.S.C. § 1291 and 18 U.S.C. § 3742 afford a defendant the right to appeal a conviction and the sentence imposed. Acknowledging that, the defendant knowingly tuaives the right to appeal this conviction and!or any sentence within [1216]*1216the statutory maximum authorized by law. In addition, the defendant agrees to waive any collateral attack to this conviction and/or sentence pursuant to 28 U.S.C. § 2255, except on the issue of ineffective assistance of counsel.
Id. at 11-12 (emphasis added).
At the sentencing hearing, the district court accepted certain stipulations in the plea agreement but rejected others. The court’s calculations resulted in an offense level of 16. With Defendant’s criminal history category of I, the Guidelines range calculated by the district court was twenty-one to twenty-seven months imprisonment. The court then considered the factors in 18 U.S.C. § 3553(a), focusing on the disparity between the mandatory five years imprisonment Elizalde faced for his gun possession conviction and Defendant’s Guidelines range, and imposed a sentence of twenty six months, followed by two years of supervised release.1 On appeal, Defendant contends the district court improperly used information Defendant provided to aid in the Government’s prosecution of Elizalde to calculate his sentence.

We review de novo the question whether a defendant’s waiver of his appellate rights in a plea agreement is enforceable. United States v. Ibarra-Coronel, 517 F.3d 1218, 1221 (10th Cir.2008). The Government may raise this issue in its principal brief, as it did in this appeal. Id. at 1221 n. 3. In determining whether Defendant’s appellate waiver is enforceable, we consider the three prongs outlined in Hahn: (1) whether this appeal falls within the scope of Defendant’s waiver of his appellate rights; (2) whether Defendant knowingly and voluntarily waived his appellate rights; and (3) “whether enforcing the waiver would result in a miscarriage of justice.” Hahn, 359 F.3d at 1325.
Defendant failed to file a reply brief and provided little analysis on the waiver question at oral argument. When asked to explain why the appellate waiver should not be enforced, Defendant’s counsel responded “that line of cases, Hahn, Porter, and Shoekey,

II.
We review de novo the question whether a defendant’s waiver of his appellate rights in a plea agreement is enforceable. United States v. Ibarra-Coronel, 517 F.3d 1218, 1221 (10th Cir.2008). The Government may raise this issue in its principal brief, as it did in this appeal. Id. at 1221 n. 3. In determining whether Defendant’s appellate waiver is enforceable, we consider the three prongs outlined in Hahn: (1) whether this appeal falls within the scope of Defendant’s waiver of his appellate rights; (2) whether Defendant knowingly and voluntarily waived his appellate rights; and (3) “whether enforcing the waiver would result in a miscarriage of justice.” Hahn, 359 F.3d at 1325.
Defendant failed to file a reply brief and provided little analysis on the waiver question at oral argument. When asked to explain why the appellate waiver should not be enforced, Defendant’s counsel responded “that line of cases, Hahn, Porter, and Shoekey, allows for an exception to [the enforcement of appellate waivers], and I respectfully submit we come underneath that exception.” When asked to elaborate which exception applied here, counsel replied, “Miscarriage of justice is the one that jumps out.” When asked, “How is there a miscarriage of justice?” counsel merely responded, “Plain error,” then alleged that the district court committed plain error when it “used information that was protected by the Kastigar debrief.”2 [1217]*1217We therefore consider only the miscarriage of justice prong of the Hahn analysis.
Enforcement of an appellate waiver results in a miscarriage of justice only if (1) “the district court relied on an impermissible factor such as race,” (2) counsel provided ineffective assistance in connection with the negotiation of the waiver, (3) “the sentence exceeds the statutory maximum,” or (4) the waiver itself is otherwise unlawful. Id. at 1327 (internal quotations omitted). The district court does not appear to have relied on an impermissible factor such as race in sentencing Defendant. Nor does Defendant allege counsel provided ineffective assistance. At his Rule 11 hearing, Defendant acknowledged that the maximum statutory penalties for his offense are up to five years in prison, a fine of $250,000, two years of supervised release, and a $100 special penalty assessment. Defendant’s sentence of twenty six months and two years of supervised release per offense, to run concurrently, does not exceed the statutory maximum. It appears Defendant’s argument, then, is that enforcing the appellate waiver would result in a miscarriage of justice because the waiver is “otherwise unlawful.”
An appellate waiver is “otherwise unlawful” only if it seriously affects “the fairness, integrity or public reputation of judicial proceedings.” Hahn, 359 F.3d at 1327. “This exception looks to whether the waiver is otherwise unlawful, not to whether another aspect of the proceeding may have involved legal error.” United States v. Smith, 500 F.3d 1206, 1213 (10th Cir.2007) (internal citations and quotations omitted). “An appeal waiver is not ‘unlawful’ merely because the claimed error would, in the absence of waiver, be appeal-able. To so hold would make a waiver an empty gesture.” United States v. Sandoval, 477 F.3d 1204, 1208 (10th Cir.2007).
When faced with appellate waivers like the one in this case, we have consistently applied this principle and enforced such waivers accordingly. In United States v. Porter, 405 F.3d 1136 (10th Cir.2005), the defendant pleaded guilty but appealed his sentence, contending, among other things, that United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005), entitled him to resentencing because the district court treated the Sentencing Guidelines as mandatory. His plea agreement included a waiver of his appellate rights, however, and we explained the relevant inquiry was not whether the defendant’s “sentence is unlawful in light of Booker’s remedial holding, but whether subsequent changes in the law render his appeal waiver itself unenforceable.” 405 F.3d at 1144. We dismissed the appeal, concluding Booker did not compel us to hold that the defendant’s waiver was unlawful and that enforcing the waiver did not “seriously affect the fairness, integrity, or public reputation of ... judicial proceedings.” Id. at 1145. Again, in United States v. Shockey, 538 F.3d 1355 (10th Cir.2008), the defendant’s plea agreement included an appellate waiver. The defendant nonetheless appealed, alleging his sentence was ambiguous and inherently contradictory and arguing that enforcing his appellate waiver in such a situation would result in a miscarriage of justice. Id. at 1356. We noted that our precedent foreclosed such an argument; despite the “inscrutable” nature of the defendant’s sentence, “enforcement of his plea agreement’s appellate waiver would not render the waiver itself unlawful.” Id. at 1357. Thus, we dismissed the defendant’s appeal. Id. at 1358.
Likewise, nothing in this case indicates that the waiver itself is unlawful. Defendant bears the burden to demonstrate that enforcing the waiver would result in a miscarriage of justice, and he has [1218]*1218not done so.3 United States v. White, 584 F.3d 935, 948 (10th Cir.2009). We reject counsel’s invitation to consider whether the merits of Defendant’s appeal reveal plain error. Because we conclude Defendant’s waiver of his right to appeal his sentence is enforceable, we dismiss Defendant’s appeal.
APPEAL DISMISSED.
