Oberski and eighteen others were charged with violations of the federal narcotics laws in a multi-count indictment. Oberski was named in 39 counts. Pursuant to a plea agreement, Oberski entered a plea of guilty to count two (continuing criminal enterprise in violation of 21 U.S.C. § 848), count fifteen (manufacturing methamphetamine in violation of 21 U.S.C. § 841(a)(1)), and count forty-two (distribution of methamphetamine in violation of 21 U.S.C. § 841(a)(1)). He was sentenced to a total of ten years imprisonment followed by a thirty-year special parole term.
I.
FACTUAL BASIS FOR GUILTY PLEA
Oberski maintains that there was an insufficient factual basis for his plea of guilty to the continuing criminal enterprise charge because the government did not establish that he was a manager or supervisor of at least five people.
A court cannot enter judgment on a plea of guilty unless it is satisfied that there is a factual basis for the plea. Fed. R.Crim.P. 11(f);
United States v. Davila,
To establish a violation under the continuing criminal enterprise statute, 21 U.S.C. § 848, the government must demonstrate that (1) the defendant engaged in a continuing series of violations of the Drug Control Act in concert with five or more persons; (2) the defendant occupied a position of organizer, a supervisory position, or any other position of management with respect to the others involved; and (3) defendant obtained substantial income or resources from his conduct.
United States v. Michel,
Oberski argues that he was only the “chemist” or “cook” and that this does not constitute a management or supervi

sory position as required by § 848. The terms “organize,” “supervise,” and “manage” are not technical terms and are interpreted according to their ordinary meanings.
United States v. Mannino,
Here, Oberski admitted to manufacturing most of the methamphetamine produced. While he claimed he was not “in charge” of the operation, he admitted to being “the main chemist” among several engaged in the enterprise, “the most experienced chemist,” and “the overall cook, chemist in the organization.” We conclude that the trial judge was not clearly erroneous in inferring from these admissions that Oberski managed and organized the methamphetamine manufacturing process.

Finally, we note that Oberski specifically admitted during the rearraignment hearing that he occupied a “management or leadership position” in the venture; because we define the terms “manager,” “organizer” and “supervisor” according to their ordinary meanings, this admission provides more evidence of a factual basis for Oberski’s guilty plea.

CUMULATIVE SENTENCES
For his conviction on count two, Oberski was sentenced to serve ten years and to forfeit the profits derived from the criminal enterprises. On count fifteen, he was sentenced to four years in prison with a special parole term of fifteen years, this sentence to run concurrently to that received for count two. On count forty-two, he was sentenced to four years with a fifteen-year special parole term, this sentence to run consecutively with that received for count fifteen. Oberski argues that the convictions and sentences imposed on counts fifteen and forty-two should be vacated because offenses under 21 U.S.C. § 841(a)(1) are lesser included offenses of a continuing criminal enterprise.
We have held that the substantive offenses underlying a § 848 violation are lesser included offenses of conducting a continuing criminal enterprise that cannot support a separate conviction or sentence.
United States v. Chagra,
On the other hand, the First Circuit has held that underlying substantive offenses
can
support a separate conviction and sentence when they are not actually relied on in establishing the continuing criminal enterprise.
United States v. Chagra,
Consequently, the two § 841(a)(1) convictions will stand if the district court did not rely on them in establishing the § 848 continuing criminal enterprise violation. The record shows that there were several other underlying offenses which the district court could have used in establishing the § 848 violation. Oberski established a factual basis for these offenses at his sentencing hearing: 4
“THE COURT: You manufactured methamphetamine twice in April 1980, once in June 1980, once in July 1980, once in August 1980, once in September 1980, four additional occasions. Did you realize that at least five other people were involved in the acquisition of chemicals, lab sites, and, prior to the manufacture and subsequent to the manufacture, five or more people were involved in the distribution of the methamphetamine?
MR. OBERSKI: Yes, sir, I did.”
These offenses independently support the § 848 conviction. Thus, the two § 841(a)(1) convictions need not have been relied upon, and can support a separate conviction and sentence.
We note that the trial judge did not specifically state that he was not relying on the § 841(a)(1) convictions to establish the § 848 conviction; however, we presume that he did so. To have relied on the § 841(a)(1) convictions would have been directly contrary to our opinions in
Chagra
and
Michel;
we presume that the trial judge followed the binding precedent of this circuit. Moreover, where a trial judge does not specifically explain the reasons for his decision, we may affirm the decision if there are obvious reasons justifying it.
Horton v. Goose Creek Independent School District,
*1034 Finding no merit in Oberski’s contentions, we affirm his conviction on all three counts.
AFFIRMED.
Notes
.
United States v. Samuelson,
.
United States v. Losada,
. Oberski consistently maintained that he never told any other chemists where to go or what to do. While this fact might preclude Oberski from being a "supervisor,” it would not prevent his classification as a "manager" or "organizer" under the terms of the statute. We hold that, in establishing that a defendant was a manager or organizer, the government need not show that the defendant had actual control over employees of the enterprise.
. The trial judge held a hearing on May 12, 1983, to accept Oberski's guilty pleas. The judge stated that he would listen to the evidence when he tried Oberski’s codefendants to determine if there was a factual basis for the § 848 violation. He then preliminarily entered a guilty plea, stating, however, that he would let Oberski know whether he intended to accept the plea at his sentencing hearing. The sentencing hearing took place on June 20, 1983. At the hearing, the trial judge questioned Oberski about the factual basis of the § 848 violation, and then, finding the factual basis sufficient, sentenced him.
. Two decisions of other circuits, seemingly contradictory to our own, are distinguishable. In
