We dismiss the appeal for the following reason:

*630 In Defendant’s direct appeal, this Court held that “Halat waived his right to appeal his sentence in exchange for the government’s agreement not to appeal a sentence imposed below the guideline range.” United States v. Sharpe, 193 F.3d 852, 871 (5th Cir. 1999). This waiver applies to a collateral attack on the sentence. In United States v. Baty, the Court explained, “We think that a defendant’s waiver of her right to appeal deserves and, indeed, requires the special attention of the district court. When a defendant waives her right to appeal, she gives up the very valuable right to correct a district court’s unknown and unannounced sentence.” 980 F.2d 977, 978 (5th Cir. 1992). The transcript reveals that the district court paid the requisite special attention. Defendant’s counsel, Mr. Chasnoff, stated, “There will be no appeal of the final sentence given by this Court ...” (emphasis added). The bottom line is that the record from the district court unambiguously establishes that Defendant chose to forsake all avenues of appeal of his sentence.

Dismissed.
