A jury convicted appellants Yolanda Bau-ta, Hector Giral and Antonio Hernandez for conspiracy to possess cocaine with intent to distribute and possession of more than 500 grams of cocaine with intent to distribute. Appellant Bauta challenges her conviction, alleging that the evidence was insufficient to support the charges against her and that the unprofessional conduct of one of the prosecution’s witnesses rendered the trial unfair. Appellant Giral also argues insufficient evidence and further maintains that the district court erroneously permitted the jury to consider evidence of a prior conviction for possession of cocaine. Appellant Hernandez protests that because he did not participate in any way in the trial, the district court erred in allowing the prosecution to introduce evidence of prior convictions for conspiracy and possession of marijuana. We AFFIRM the determinations of the district court with regard to all the appellants and the jury verdict convicting Bauta and Hernandez. We REVERSE the conviction of Giral.
I. BACKGROUND
On November 16, 1987, Detective Pablo Garcia, through arrangements set up by a confidential informant, was contacted on his beeper by Roberto Mercado. When Detective Garcia called the number left by Mercado on the beeper, the woman who answered the phone, later ascertained to be appellant Bauta, identified the location as Seventh Avenue Auto Sales before forwarding the call to Mercado. In the ensuing six telephone conversations between Mercado and Garcia, which Garcia recorded, they negotiated a deal to exchange one kilogram of cocaine for $14,000. In the last conversation, Mercado told Garcia that the person delivering the cocaine would be at Seventh Avenue Auto Sales in forty minutes. At that point, Garcia gathered several of his fellow officers at the Coral Gables Police Department and set up surveillance around Seventh Avenue Auto Sales to monitor whatever might transpire in his transaction with Mercado.
Garcia and the informant met Mercado at the car lot of Seventh Avenue Auto Sales at approximately 4:30 P.M. When Garcia asked Mercado for the “merchandise,” Mercado replied, “They have it with them,” and pointed to a gray car occupied by appellants Bauta and Hernandez. R2-40-41. However, after Mercado introduced Garcia to Bauta and Hernandez, it became evident that Bauta and Hernandez did not have the cocaine. The four of them 1 waited and chatted at the car lot until sometime between 6 and 6:30 P.M. when a beige, four-door, 1982 Mercury Cougar drove onto the car lot. Hernandez indicated that this was the car for which they had waited. Garcia told Mercado to have the driver of the Cougar park next to Garcia’s car, ostensibly to facilitate the deal, but actually to allow the surveillance team to best observe what would occur. The Cougar was occupied by the driver, Reinaldo Aquino, and a passenger, appellant Giral.
Both Aquino and Giral got out of the car and went to the trunk. Garcia asked Aqui *517 no whether he had “it” with him. Aquino replied that he had only one and if Garcia wanted another one, he would have to come to “our” house to get it. R2-49. Garcia then asked to check it, and Aquino opened the trunk as Garcia and Giral stood by. Aquino handed Garcia a blue and white plastic bag containing a package wrapped in yellow tape, which later proved to contain cocaine. Just as Garcia received the package, Giral, according to Garcia, “picked up on something,” and walked away from the ear to the Burger King across the street. R2-49-52. Moments later, Garcia gave the arrest signal. Bauta, Hernandez, Mercado and Aquino were arrested at the car lot. Giral was arrested at Burger King, where he was found at a pay phone, holding on to a dead receiver.
Mercado and Aquino eventually pleaded guilty to possession with intent to distribute; the government dismissed the conspiracy charge against them. Bauta, Hernandez and Giral pleaded not guilty. After a two-day trial, the jury found all three guilty of conspiring to possess with intent to distribute and possessing with intent to distribute more than 500 grams of cocaine.
II. STANDARD OF REVIEW
Three types of grievances are lodged by appellants. Bauta and Giral challenge the sufficiency of the evidence to convict them. Giral and Hernandez question the admission under Federal Rule of Evidence 404(b) of extrinsic evidence of their prior crimes. Bauta additionally disputes the district court’s denial of defense counsels’ motions for a mistrial to remedy the prejudice to her right to a fair trial allegedly caused by Garcia’s unprofessional conduct as a witness for the government.
This court most recently restated the standard of review for sufficiency of the evidence in
United States v. Poole,
This Court must view the evidence in the light most favorable to the government, Glasser v. United States,315 U.S. 60 , 80,62 S.Ct. 457 , 469,86 L.Ed. 680 (1942), and determine whether the jury could have found defendant guilty beyond a reasonable doubt. See United States v. O’Keefe,825 F.2d 314 , 319 (11th Cir.1987). The evidence need not be inconsistent with every reasonable hypothesis except guilt, and the jury is free to choose between or among the reasonable conclusions to be drawn from the evidence presented at trial. See United States v. Bell,678 F.2d 547 , 549 (5th Cir. Unit B 1982) (en banc), aff'd on other grounds,462 U.S. 356 ,103 S.Ct. 2398 ,76 L.Ed.2d 638 (1983).
“ ‘In applying this standard all reasonable inferences and credibility choices must be made in favor of the jury verdict, and that verdict must be sustained if there is substantial evidence to support it_’”
United States v. Pintado,
The district court’s admission of the extrinsic offense evidence against Giral and Hernandez “will not be reversed absent a clear abuse of discretion.”
United States v. Edwards,
III. DISCUSSION
A. Sufficiency of the Evidence
1. Conspiracy
For us to uphold the conspiracy convictions, the government must have proven beyond a reasonable doubt that a conspiracy existed, that appellants knew of the conspiracy, and that appellants voluntarily joined the conspiracy.
See, e.g., United States v. Alvarez,
Appellant Bauta
We believe that in Bauta’s case, the government satisfactorily proved all three elements to convict Bauta of conspiring to possess cocaine with intent to distribute. Clearly there was an agreement to violate the narcotics laws involving, at the very least, Mercado and Aquino. Although the testimony of the government’s witnesses and Bauta’s witnesses differs on many points,
4
we are constrained to make all credibility choices in favor of the jury verdict.
See Pintado,
Garcia’s statements are corroborated by the testimony of Sergeant Joe McNichol who was in the surveillance van with another detective, monitoring the events in the car lot both visually and aurally. Sergeant McNichol did not understand most of the-discussion that took place between Garcia and the others, as they spoke in Spanish. McNichol did see, however, when Bauta wrote on a piece of paper and handed it to Garcia. R2-97. He also saw Bauta and Hernandez waving down Aquino’s car. Id. Finally, he too placed Bauta at the trunk of Aquino’s car as the cocaine was being delivered. R2-98.
These facts indicate that Bauta was more than simply present at the scene of the crime, more than a knowledgeable bystander, more than merely associated with the other conspirators. Her knowledge of and participation in the conspiracy is shown by her checking by telephone to ensure that the deal would go through, by her offer to complete the transaction at her house if Garcia could not wait for the cocaine to be delivered at the car lot, and by her recognition and waving down of Aquino’s car. The jury had sufficient evidence to find Bauta guilty beyond a reasonable doubt of conspiracy under 21 U.S.C. section 846.
Appellant Giral
The government’s case against Giral is far less convincing. Essentially, the government’s case against Giral consists of Giral’s presence in Aquino’s car and at the trunk when Aquino delivered the package to Garcia, Giral’s walking away after catching Garcia’s eye, Giral’s talking to a dead phone, and Giral’s prior conviction of cocaine possession. R2-48-52, 83, 100-03, 136. Yet Giral’s mere association with Aquino or presence at the transaction does not prove that he was a part of the conspiracy. Even in conjunction with his “flight” to Burger King Giral’s presence cannot support a conspiracy conviction.
See Pintado,
Viewing the facts in the light most favorable to the government, we can surmise that Giral’s association with Aquino may have been criminal, that Giral’s presence at the scene of the crime could have been because of his involvement in the conspiracy, that Giral’s abrupt departure might have occurred because he caught on to Garcia, was guilty and hoped to avoid arrest, and that Giral’s intent in this case could have been identical to his intent in the narcotics crime for which he was convicted in 1985. We cannot find, however, that the government proved beyond a reasonable doubt that Giral was a member of this particular conspiracy to sell a kilogram *520 or two of cocaine to Garcia. We hold that there was insufficient evidence to convict Giral of conspiracy under 21 U.S.C. section 846.
2. Possession with Intent to Distribute
Appellants were also convicted under 21 U.S.C. section 841(a)(1). 5 For these convictions to stand,
the government had to prove three elements: (1) knowledge; (2) possession; and (3) intent to distribute. All three elements can be proven by either direct or circumstantial evidence. Evidence of surrounding circumstances can prove knowledge. Constructive possession is sufficient for the possession element, and can be established by showing ownership or dominion and control over the drugs or over the premises on which the drugs are concealed. Intent to distribute can be proven circumstantially from, among other things, the quantity of cocaine....
United States v. Poole,
Again the evidence sufficiently supports Bauta’s conviction while failing to prove beyond a reasonable doubt Giral’s guilt. The same facts which sustain the conspiracy conviction against Bauta make it plain that, as one of the conspirators, she constructively possessed what she knew to be approximately one kilogram of cocaine and facilitated the exchange of that cocaine for $14,000.
Cf. United States v. Rosado-Fernandez,
B. The 404(b) Evidence
The government introduced evidence of prior convictions against appellants Giral and Hernandez to prove the element of intent required for the crimes of conspiracy and possession with intent to distribute a controlled substance. The seminal case in this Circuit on the admissibility of evidence of extrinsic offenses is
United States v. Beechum,
[Rule 404(b) ] 6 follows the venerable principle that evidence of extrinsic offenses should not be admitted solely to demonstrate the defendant’s bad character.... Without an issue other than mere character to which the extrinsic offenses are relevant, the probative val *521 ue of those offenses is deemed insufficient in all cases to outweigh the inherent prejudice. Where, however, the extrinsic offense evidence is relevant to an issue such as intent, it may well be that the evidence has probative force that is not substantially outweighed by its inherent prejudice. If this is so, the evidence may be admissible.
Id.
at 910. The test for admissibility breaks down into a two-part test: first, is the extrinsic offense evidence relevant to an issue apart from the defendant’s character; and, second, does the evidence meet the requirements of Fed.R.Evid. 403.
7
Id.
at 911;
see also Huddleston v. United States,
In the context of intent,
the relevancy of the extrinsic offense derives from the defendant’s indulging himself in the same state of mind in the perpetration of both the extrinsic and charged offenses. The reasoning is that because the defendant had unlawful intent in the extrinsic offense, it is less likely that he had lawful intent in the present offense.
Beechum,
Giral does not deny that he had been convicted in 1985 for possession with intent to distribute cocaine. Hernandez, however, contests whether the government provided enough evidence so that a jury could reasonably conclude that he was the Antonio Hernandez convicted of conspiracy and possession with intent to distribute marijuana in 1981. The evidence before the judge was that appellant was identified as Antonio Hernandez, that an Antonio Hernandez had been convicted by a federal court for conspiracy and possession and sentenced to a six-year term, and Detective Garcia’s unchallenged testimony that, while they were waiting for the cocaine to arrive, appellant Hernandez had told Garcia that he was on probation. 8 Rl-55; R2-43, 136. We believe that a reasonable jury could conclude from these facts that the Hernandez convicted in 1981 was the same Hernandez before them at trial. The trial court did not abuse its discretion in determining that the evidence of the Hernandez conviction was relevant to appellant Hernandez.
Both appellants contend that the extrinsic offense evidence served only to depict them as convicted criminals with a propensity toward crime. The government asserted at trial that its introduction of this evidence bolstered its proof of the criminal
*522
intent of appellants. Under
Beechum,
if the intent involved in the extrinsic offense is the same as that of the charged offense, then the extrinsic act is “relevant ... to an issue other than propensity because it lessens the likelihood that the defendant committed the charged offense with innocent intent.”
Finally, both appellants argue that the probative value of the extrinsic offense evidence was substantially outweighed by its undue prejudice because neither of them contested the issue of intent, the extrinsic and charged offenses had not been shown to be sufficiently factually similar, and the time lapse between the two sets of offenses greatly diminished the probity of the prior acts. None of these arguments have any validity. Although neither Giral nor Hernandez participated in the trial except to cross-examine the government’s witnesses, both of them pleaded not guilty to the charges brought against them. The law in this Circuit provides that intent becomes a material issue whenever a defendant pleads not guilty to a charge of conspiracy unless the defendant affirmatively withdraws the issue of intent from the case.
United States v. Roberts,
The factual differences between the prior bad acts of Giral and Hernandez and the crimes charged in this case do not strike us as significant. We do not see that the trial judge abused his discretion in finding similarity between Giral’s possessing with intent to distribute 24 grams of cocaine in New Orleans and Giral’s allegedly conspiring to possess and possessing with intent to distribute more than 500 grams of cocaine in Miami.
Cf. United States v. Hicks,
With regard to the interval between the prior offenses and the crimes charged here, the court in
Hitsman
said that 404(b) evidence would be admissible where “the offenses were only two or three years apart[.]”
Id.
Giral’s conviction clearly falls within this limit. Hernandez’s six-year-old conviction might carry far less probative weight due
*523
to its “temporal remoteness,”
Beechum,
Finally, the district court limited the prejudicial effect of the extrinsic offense evidence by giving the jury cautionary instructions, when the evidence was introduced and again at the close of trial, on the limited use of such evidence.
See United States v. Boon San Chong,
C. Denial of Mistrial
Bauta claims that Detective Garcia made several statements during his testimony that individually and cumulatively impaired her right to a fair and impartial trial, and that the trial judge erred in not granting a mistrial based on Garcia’s conduct. Ordinarily we review such a claim by determining whether the misconduct prejudiced appellant’s substantial rights and whether other significant evidence of appellant’s guilt decreased the possibility that the improper testimony had any meaningful effect on the jury verdict.
United States v. Anderson,
“The plain-error doctrine_ authorizes the Courts of Appeals to correct only ‘particularly egregious errors’ ... that ‘seriously affect the fairness, integrity or public reputation of judicial proceedings[.]’ ... [T]he plain-error exception ... is to be ‘used sparingly, solely in those circumstances in which a miscarriage of justice would otherwise result.’ ”
United States v. Young,
D. Conclusion
For the foregoing reasons, we AFFIRM the convictions of Yolanda Bauta and Anto *524 nio Hernandez; we REVERSE the conviction of Hector Giral for insufficiency of evidence.

Bauta and her witnesses give an account of a single mother of good reputation trying to provide for her family despite a debilitating illness who, after being fired from her job at Seventh Avenue Auto Sales, was given one last chance by her boss to make a quick $100 commission by showing cars to Hernandez. After picking up Hernandez from some unidentified intersection, she drove him back to the car lot, where she encountered the informant, an ex-employee of Seventh Avenue Auto Sales, Mercado, her former co-worker and Garcia, to whom she was introduced. Because of her illness, she allowed Hernandez to inspect the cars himself and stayed by her car talking to the other men and various persons whom she knew from work, except for when she went into the office to telephone her children. Drugs were never discussed at any time. When Aquino’s car pulled up, she stated that his car was parked the equivalent of two football fields away from where she was, and even further from Hernandez. She had no idea what had been taking place until the police appeared and she was arrested, either a few seconds or seven to ten minutes later, according to two different witnesses.
