olina on a single count of conspiracy to possess cocaine with intent to distribute and to distribute, along with eleven others, thirty kilograms of cocaine from about April 1, 1987, through about January 18, 1988. According to the indictment, the cocaine was transported to North Carolina by eo-indietee John Edward Comer, who in turn utilized a redistribution network which he had established. Vinson was alleged to be a member of this redistribution network. Vinson cooperated with government investigators and, in return, the government agreed to request that any sentence imposed not exceed five years imprisonment.
Prior to sentencing, a presentence report was prepared by the court’s probation officer. Guidelines § 6A1.1. Based on interviews with a federal agent, David Ramsey, the probation officer noted in his report that Vinson “probably was responsible for assisting Comer in getting involved in the cocaine business.” Also, the report stated that “Vinson allegedly introduced Comer to a number of contacts and was initially one of Comer’s lieutenants until he became ‘slack’ in paying for cocaine and thus moved down the hierarchy to about the third-man level position.”
The probation officer began his sentence calculation by using the base offense level for a crime involving cocaine of between 15 and 49.9 kilograms. Guidelines § 2D1.1(a)(3). This level of 34 was increased by 2 levels due to the probation officer’s finding that Vinson was at one time a supervisor in the criminal activity. Guidelines § 3Bl.l(c). The offense level was then decreased by 2 levels for acceptance of responsibility. Guidelines § 3El.l(a). Based on a total offense level of 34 and a criminal history category of I, the guideline range was determined to be 151-188 months. Guidelines Chap. 5, Part A. The statutory sentence range was stated to be a minimum of ten years to a maximum of life.1 The report concluded by
noting that the plea agreement required the government to recommend a departure from the guidelines sentence on the basis of Vinson’s “substantial assistance.” Guidelines § 5K1.1.
Vinson filed an objection to the presen-tence report. Guidelines § 6A1.3(a). The crux of his objection was that he purchased less than xk kilogram of cocaine from Comer for personal use only, that his involvement with Comer ended in May, 1987, after his (Vinson’s) arrest on state charges, that he neither knew of nor participated in the overall conspiracy, and that he never sold or transported cocaine. Vinson points to a statement given by Comer to federal agent Ramsey which detailed Vinson’s involvement. According to Vinson, this statement substantiates his claim that he purchased only fourteen ounces, or 396.9 grams, of cocaine from Comer. At the December 19, 1988, sentencing hearing, Vinson’s counsel stipulated that a factual basis for the plea of guilty existed on the basis of the evidence presented in an earlier trial involving one of Vinson’s coconspirators. After the court announced that the plea was accepted, Vinson’s counsel reiterated his objections to the presentence report. The court accepted the presentence report and granted the government’s motion for a downward departure on the basis of Vinson’s “substantial assistance.” The maximum sentence contemplated by the plea agreement, i.e. 60 months, was imposed.
II.
On appeal, Vinson contends that the sentencing court was required under the due process clause to find beyond a reasonable doubt every fact necessary to increase the offense level under the Guidelines; alternatively, Vinson argues for a clear and convincing standard of proof for such facts. In United States v. Urreqo-Linares, 879 F.2d 1234 (4th Cir.1989), this Court adopted a preponderance standard

The report’s statement that Vinson’s conviction carried a statutory minimum term of ten years is incorrect. Vinson was convicted of conspiracy to violate § 841(a)(1) and not of the substantive offense itself. Therefore, the minimum penalty provisions of § 841(b)(1)(A) are inapplicable. The only statutory restraint under § 846 is that the sentence may not exceed the maximum prescribed for the substantive offense. United States v. Campbell, 704 F.Supp. 661, 663-65 (E.D.Va.1989).
