OPINION

Carl McElveen appeals the district court’s judgment of sentence in which the court sentenced him to 75 months of imprisonment following his guilty plea. The plea was entered pursuant to a plea agreement in which McElveen waived his right to appeal absent certain contingencies that are not present. For the reasons that follow, we will affirm.

McElveen asks us to review the reasonableness of his sentence pursuant to United States v. Booker, 543 U.S. 220, 125 S.Ct. 738, 160 L.Ed.2d 621 (2005). However, as noted, he entered into a plea agreement in which he expressly waived all his rights to appeal or collaterally attack his conviction, sentence, or any other matter relating to his prosecution, SuppApp. at 5.

Such waivers are valid and are strictly construed if entered into knowingly, voluntarily and intelligently. United States v. Khattak, 273 F.3d 557, 562-63 (3d Cir. 2001). Nothing on this record suggests that McElveen’s plea agreement was not entered into knowingly, voluntarily or intelligently. Thus absent a miscarriage of justice, McElveen’s waiver effectively deprives us of jurisdiction to review the merits of his appeal. Id. Here, there is not even a suggestion that enforcing the waiver would result in any such miscarriage.

McElveen’s offense level under the Sentencing Guidelines was 23, and his criminal history category was “V.” This resulted in a sentencing range of 84-105 months of imprisonment as stated in the Presentence Investigation Report. App. 43. The court imposed a sentence of 75 months incarceration, which fell below the applicable Guideline range. There was no upward departure, and the sentence is clearly less than the statutory maximum.

McElveen argues that Booker grants the right to appeal the reasonableness of his sentence despite his waiver. However, an intervening court decision does not negate the waiver in his plea agreement. United States v. Lockett, 406 F.3d 207, 213 (3d Cir. 2005). We have held that, despite the sea change that followed in the wake of Booker, we will enforce the terms of a valid waiver of the right to appeal from a sentence imposed pursuant to a guilty plea. Id. at 213-14. Moreover, before sentencing, all parties and the sentencing court recognized the impact of Booker, and understood that the Guidelines had become advisory. App. 25.

*114 Accordingly we will affirm the judgment of sentence.
