OPINION

Maurice Samuel appeals his sentence of seventy-eight months’ imprisonment for conspiracy to distribute cocaine, two counts of distribution of cocaine, and aiding and abetting distribution of cocaine in violation of 21 U.S.C.A. §§ 841(a)(1), 846 (West 1999); 18 U.S.C. § 2 (1994). On appeal, Samuel challenges the district court’s calculation of drug quantity attributed to him at sentencing. We affirm.

This court reviews the district court’s calculation concerning the amount of drugs attributable to a defendant for sentencing purposes for clear error. United States v. Randall, 171 F.3d 195, 210 (4th Cir. 1999). A conspirator may be held accountable for all quantities of contraband attributable to the conspiracy that were reasonably foreseeable and within the scope of the conspiratorial agreement. United States v. Gilliam, 987 F.2d 1009, 1012-13 (4th Cir. 1993); U.S. Sentencing Guidelines Manual, § lB1.3(a)(l)(B) & comment, (n.2). We find the district court did not clearly err in attributing to Samuel 418 grams of cocaine found in the search of Samuel’s apartment or 481.48 grams of cocaine converted from monies seized during a stop of his co-conspirators. Further, we are satisfied the district court’s findings were sufficiently particular.

We grant Samuel’s pro se motion to file a supplemental brief and have considered the arguments raised therein. For the above reasons, we affirm his sentence. 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.

AFFIRMED.
